[0002]
[Prior art]
2. Description of the Related Art In recent years, flat panel displays such as liquid crystal devices and EL (Electro Luminescence) display devices have been widely used as display units of various electronic devices such as mobile phones and portable electronic terminals. In this electronic apparatus, the flat panel display is generally disposed at a predetermined position in the electronic apparatus by being supported by a frame having a predetermined shape. Conventionally, the flat panel display is firmly fixed and supported in a state of being in close contact with the frame, that is, without a clearance.
[0003]
[Problems to be solved by the invention]
By the way, in said flat panel display, in order to support electro-optical substances, such as a liquid crystal, an EL element, etc. which are the main elements for performing a display, support members, such as glass and a plastic, are used. For example, a liquid crystal device generally includes a pair of substrates formed of glass, plastic, etc., and sandwiches liquid crystals, and modulates light passing through the liquid crystal layer for each pixel, thereby providing letters, numbers, etc. on the surface of one substrate. Is displayed.
[0004]
Support members such as glass substrates generally have the property of being easily damaged by impact. When a flat panel display is attached in close contact with a frame like a conventional electronic device, when an impact is applied to the electronic device by dropping the electronic device or the like, the impact is applied to the support member of the flat panel display through the frame. As a result, the support member may be cracked or damaged.
[0005]
The present invention has been made in view of the above problems, and an object thereof is to reliably prevent a flat panel display used in an electronic device from being damaged by an impact.

If the frame for supporting the flat panel display is made of a light guide, it is not necessary to provide a dedicated frame, so that the cost can be reduced and the support structure can be made compact.
[0009]
Next, in the support structure configured as described above, the flat panel display can be a liquid crystal device. In general, a liquid crystal device is formed by holding a liquid crystal between a pair of substrates, and these substrates are often formed of glass. Since glass has the property of being easily damaged by impact, the conventional support structure, that is, the structure in which the flat panel display is supported in close contact with the frame, has a high risk of being damaged by impact. On the other hand, if a filling member is interposed between the flat panel display and the frame as in the present invention, the glass substrate and the like can be effectively protected from impact.

Here, the non-light-transmitting material includes not only the material itself that does not transmit light, but also the material itself is translucent but forms a black ink layer or other light shielding layer on it. This also includes the case where the whole becomes non-light-transmitting.
[0011]
Next, in the support structure having the above configuration, it is desirable that the filling member is provided over substantially the entire outer periphery of the flat panel display. According to this configuration, the flat panel display can be prevented from being damaged by an impact, and moisture can be prevented from entering the flat panel display from the outside. That is, moisture resistance can be ensured.
[0012]
Next, in the support structure having the above-described configuration, the filling member can be provided at a corner of the outer periphery of the flat panel display. The filling member may be provided in an intermediate portion other than the corners on the outer periphery of the flat panel display.
[0013]
Next, an electronic apparatus according to the present invention is formed to be larger than a flat panel display, a light guide having a recess for storing the flat panel display with a space, and an outer edge of the flat panel display. A frame that locks the side surface of the light guide with a locking piece, an elastic filling member that is attached to the entire inner periphery of the frame, and a housing that surrounds the light guide and the filling member. The filling member is formed of a non-light-transmitting material, and when the locking piece of the frame is locked to the side surface of the light guide, the filling member is a space in the recess. It is provided in the whole area of the outer periphery of the flat panel display.
[0014]
According to the electronic device having this configuration, the flat panel display is not supported in close contact with the frame, but an elastic filling member is interposed between them, so that even if an external impact is applied, the impact Can be absorbed by the filling member, thus preventing damage to the flat panel display.
[0015]
Next, in the electronic apparatus having the above-described configuration, the frame is preferably a light guide that guides light to the flat panel display. According to this configuration, light can be supplied to the flat panel display by the light guide. If the light guide is arranged on the side opposite to the observation side of the flat panel display, a so-called backlight is formed. On the other hand, if the light guide is arranged on the observation side of the flat panel display, a so-called front light is formed. If the frame for supporting the flat panel display is formed of a light guide, it is not necessary to provide a dedicated frame, so that the cost can be reduced and the connection structure can be made compact.
[0016]
Next, in the electronic apparatus having the above configuration, the flat panel display can be a liquid crystal device. In general, a liquid crystal device is formed by holding a liquid crystal between a pair of substrates, and these substrates are often formed of glass. Since glass has the property of being easily damaged by impact, the conventional connection structure, that is, the structure in which the flat panel display is supported in close contact with the frame, has a high risk of being damaged by impact. On the other hand, if a filling member is interposed between the flat panel display and the frame as in the present invention, the glass substrate and the like can be effectively protected from impact.
[0017]
Next, in the electronic apparatus having the above-described configuration, it is preferable that the filling member is formed of a non-light transmissive material. According to this configuration, when an illuminating device such as a backlight or a front light is disposed inside the electronic apparatus, light from the illuminating device can be prevented from leaking to the outside. Here, the non-light-transmitting material includes not only the material itself that does not transmit light, but also the material itself is translucent but forms a black ink layer or other light shielding layer on it. This also includes the case where the whole becomes non-light-transmitting.
[0018]
