DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pattern light emitting organic dispersion type EL device, and more particularly, to a pattern light emission type organic dispersion type EL device suitably used for various relatively large signs and signs. It relates to an element.

[0002]

2. Description of the Related Art Basically, an organic dispersion type EL device has a reflective insulating layer and a light-emitting layer sequentially disposed between a back electrode and a transparent electrode, and is in contact with the light-emitting layer on the transparent electrode side to collect the current. Is provided. Usually, an aluminum foil is used as the back electrode, and a so-called ITO film in which an ITO film is formed on the surface of a transparent plastic film is used as the transparent electrode. Such EL elements are being used as display means for road signs, signboards, and the like by adopting a pattern light emitting method.

[0003] Pattern light emission in an EL element is performed to achieve a certain display by a combination of a light-emitting portion and a non-light-emitting portion. At the same time, a power-saving effect is expected by the formation of the non-light-emitting portion. Especially in the case of road signs, etc.
The power supply to the L element is preferably performed using a combination of a solar cell and a storage battery, and therefore, its power saving effect is important.

[0004] The above-mentioned pattern light emission system includes (1)
A method of etching and removing a transparent conductive layer (ITO layer) corresponding to a non-light-emitting part, a method of not providing a light-emitting layer in a non-light-emitting part, a method of providing only a back electrode corresponding to a light-emitting part, (4) A method of forming a light-shielding layer on the film surface of a transparent electrode corresponding to a non-light emitting portion, and (5) a method of forming an electrically insulating resin layer on a back electrode corresponding to a non-light emitting portion. However, the methods (1) to (3) are not always simple and easy, and the methods (4) and (5) do not provide the expected power saving effect.

[0005] Usually, an EL element is manufactured by the following method. That is, after forming a reflective insulating layer by applying a reflective insulating layer paste on the back electrode and heating and drying, a light emitting layer is formed by applying a luminescent layer paste and drying by heating, After forming a current collecting band on the light emitting layer by means of printing a conductive paste,
It is manufactured by heat laminating a transparent electrode.

Therefore, the EL element involves application and drying of a paste, and since an ITO film having a metal oxide film formed on the surface thereof is usually used as a transparent electrode, the size or size of the ITO film is limited in the manufacturing process or the size of the ITO film. Due to restrictions, the area of one sheet (light emitting area) is limited, and it is difficult to perform pattern light emission over a wide area.

Specific examples include an acrylic resin, a polyester resin, a polyurethane resin, a polybutadiene resin, an epoxy resin, and a phenoxy resin.

In the present invention, an ionizing radiation-curable resin can be suitably used as the electrically insulating resin. Examples of the ionizing radiation include an electron beam and an ultraviolet ray. As the electron beam, an electron beam having an energy of usually 50 to 1000 KeV, preferably 100 to 300 KeV is used. In addition, the electron beam is of the Kotzkrold-Walton type,
It can be easily emitted from various electron beam accelerators such as bandeograph type, resonance transformer type, insulating core transformer type, linear type, dasnamitron type and high frequency type. Ultraviolet light can be easily obtained from a light source such as a low-pressure mercury lamp and a metal halide lamp.

The organic dispersion type EL device of the present invention can be manufactured by the following method. First, according to the above-described conventional method, a reflective insulating layer and a light emitting layer are sequentially formed on a back electrode corresponding to a plurality of EL elements. Next, an electrically insulating resin coating layer for a non-light-emitting portion formed over a light-emitting portion and a non-light-emitting portion pattern over the surface of the light-emitting layer or the surface of the transparent electrode corresponding to each EL element was formed.

The EL device according to the second aspect of the present invention uses a plurality of EL devices (12) packaged with a transparent moisture-proof film, except that the ends are overlapped with each other and integrated. This is the same as the EL element according to the first aspect of the present invention. Therefore, in the case of the EL element according to the second aspect of the present invention, the non-light-emitting portion and the non-light-emitting portion are formed between the light-emitting layer and the transparent electrode of each EL device and formed in the pattern of the light-emitting portion and the non-light-emitting portion. Provide an electrically insulating resin layer for the light-emitting part, heat-laminate each transparent electrode on each light-emitting layer to form a structure in which an insulator layer and a light-emitting layer are sandwiched between the electrodes, and package with a moisture-proof film. Then, a plurality of EL elements are formed in advance, and then the ends of each EL element are overlapped with each other to be integrated.

By the way, in the above EL element, as shown in FIG. 4, an overlapping line (13) exists.
The superposition line (13) poses little problem since it is not visible at night when the EL device of the present invention is mainly used. However, in order to make the overlapping line (13) in the light emitting portion difficult to see, in the present invention, the transparent colored plate (1) is provided on the light emitting surface of the integrated EL element.
It is preferable to arrange 5). As the transparent colored plate (15), for example, a milky white polyester sheet containing a white pigment can be suitably used.

The symbol (14) shown in FIG.
A support plate for holding the element (12), (16) is a case formed in a square shape by a frame having a U-shaped cross section for accommodating each EL element (12). These support plate (14) and case (16) are appropriately used for the above-described EL element according to the second aspect of the present invention.

The EL device of the present invention can be connected to an AC power supply via an inverter as required.
The inverter increases the emission voltage of the packaged EL element by increasing the frequency of the alternating voltage. And the EL of the present invention.
According to the element, a remarkable power saving effect is achieved by the non-light emitting portion having the specific configuration described above. In light emission of the EL element, various blinking methods such as full blinking and alternate blinking can be employed.
