複雑になり不良となる確率も高い。In the manufacturing method of the multicolor liquid crystal display device explained in FIG. 5 and FIG. Requires. As color filter patterns become more precise, it becomes more difficult to make photomasks without defects, which makes them more expensive. Also, alignment of the color filter and photomask is required during exposure, and the finer the pattern, the more technically difficult it becomes, and the more complicated the equipment and fabrication become, the higher the probability of failure.

By coating the entire surface of the filter with a photosensitive material and exposing the photosensitive material to light of 400 nm or less from the back of the color filter, only the photosensitive material in the gap between the color filters is exposed and developed, allowing the color filter to be formed with high precision. A light shielding film is formed only in the gap.

ば、その光源を用いる事で本発明の目的ば遠戚される。Currently, color filters for multicolor display devices often use the three primary colors of additive color mixture, that is, red, green, and blue, and their spectral characteristics are as shown in Figure 4, with transmittance of almost 0 below 400 nm. It becomes. That's 400n
It can be used as a photomask for light of m or less, indicating that self-alignment is possible. However, - the light source used to expose the resist for boat fishing is 40
There are few that generate only light of 0 nm or less. A mercury lamp or a metal halide lamp is commonly used as a light source. For example, the emission spectrum of a high-pressure mercury lamp is g-line (435 nm), hvA, etc., as shown in Figure 4.
There are three main types: (405 nm) and i-line (365 nm), and they vary in strength and spread depending on the type.In the case of metal halide lamps, they often have a broad spread rather than a clear line spectrum. If only i-line (365 nm), which is 400 nm or less, is used as a light source, 4
If there is a light source that hardly emits light of 00 nm or more, the purpose of the present invention can be achieved by using that light source.

Lines (405nm) are also generated, so blue filters in particular transmit around 450nm, causing light leakage, and the photosensitive material on the color filter, which should not be exposed, is exposed, and the color cannot be removed by development. A light shielding film is also formed on the filter.

ある。Therefore, the present inventors added an ultraviolet transmitting optical filter that blocks light of 400 nm or more and has the spectral characteristics shown in Figure 4 to the conventional light source, and used the light that passed through this optical filter to cover the color filter with a photo mask. We have discovered that by exposing with self-alignment, it is possible to completely eliminate the leakage of light that passes through the color filter, and it is possible to obtain high resolution. According to this method, by simply adding an ultraviolet-transmitting optical filter to a conventional exposure light source, it is possible to form a light-shielding film very easily and accurately only in the gaps between color filters, making it extremely useful in practice. It is.

法等があるが本発明では特に限定されるものではない。In addition, methods for imparting light-shielding properties to the photosensitive material remaining in the gaps between the color filters include coating a negative photoresist mixed with a light-shielding substance such as carbon as a photosensitive material, or applying a negative-tone dyeable material. There are methods such as applying a resist, exposing it to light, developing it, and then dyeing it with a black dye to impart light-shielding properties, but the present invention is not particularly limited thereto.

載の多色表示装置の製造方法。[Claims] [1] A method for manufacturing a multicolor display device using color filters, including the steps of: (1) forming a plurality of color filters on a transparent substrate; (2) applying a photosensitive material on the color filters; (3) Using the color filter as a photomask, the photosensitive material is exposed to light of 400 nm or less from a light source on the back of the substrate. (4) By developing, the photosensitive material is applied only to the gap between the color filters. 1. A method for manufacturing a multicolor display device, comprising the step of leaving a light-shielding film on the screen and forming a light-shielding film. [2] The method for manufacturing a multicolor display device according to claim 1, wherein the photosensitive material is a negative photoresist mixed with a light-shielding substance. [3] The photosensitive material is a negative dyeable photoresist, and after being left only in the gap between the color filters, it is dyed with a black dye to form a light-shielding film. A method for manufacturing a multicolor display device. [4] The multicolor display device according to claim 1, wherein the light of 400 nm or less is produced by adding an optical filter to the light source that blocks light of 400 nm or more and transmits light of 400 nm or less. Production method. [5] The method for manufacturing a multicolor display device according to claim 1, wherein the light source is a mercury lamp or a metal halide lamp. [6] The color filter forms a plurality of conductive layers arranged insulated from each other on a substrate, and then electrodeposition is performed on the conductive layers from a solution in which an electrodepositable polymer and a dye are dispersed. 2. The method of manufacturing a multicolor display device according to claim 1, wherein the multicolor display device is selectively formed by.
