のカラーフィルターの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of manufacturing a multicolor display device using a color filter, and particularly to a method of manufacturing a color filter with a light-shielding film for improving display quality.

簡便な方法で多大な効果をあげるものである。In order to eliminate the drawback that precise patterning is required when forming a light-shielding film in the gaps between each color of a color filter, the present invention forms a dyeable material on a substrate in advance, and a transparent electrode is placed on it. By sequentially forming a transparent electrode and using it as an anti-dyeing mask to prevent the transparent electrode from being dyed, only the dyeable layer exposed in the gap between the transparent electrodes is colored to become a light-shielding film, and then a color filter is formed on the transparent electrode. ,
This is a simple method with great effects.

, 33'' are color filters having patterns that match the transparent electrodes, each having a different tone. 34 is a second transparent substrate on which a second transparent electrode 35 is formed, and is opposed to the transparent substrate 41. A liquid crystal 36 is sandwiched in the gap to form a multicolor display device.

示装置において透明電極の間隙部分からもれてくる迷光
は極力おさえる事が色の純度を保つために必要である。When this multicolor display device is sandwiched between a polarizer and an analyzer and a voltage is selectively applied to the liquid crystal via transparent electrodes, there will be parts that transmit light through the color filter and parts that do not transmit any light, resulting in a color display. It becomes possible. In such a multicolor display device, it is necessary to suppress stray light leaking from the gaps between the transparent electrodes as much as possible in order to maintain color purity.

加時に透過となるような表示モードを選択した場合には
間隙は常に白の表示となり、色の純度は得られない。However, if the polarizer and analyzer are arranged so that the color is black when no voltage is applied, the thickness of the liquid crystal layer differs between the electrode part where the color filter is located and the gap part by the thickness of the color filter. If an attempt is made to sufficiently block light from a portion, stray light will occur in the gap due to light interference due to deviations in the thickness of the liquid crystal layer. Furthermore, if a display mode is selected in which the display becomes transparent when no voltage is applied, the gap is always displayed as white, and color purity cannot be obtained.

However, it is difficult to form a light-shielding layer only in the very fine gaps between color filters, and patterning must be performed using a fine photomask, which significantly complicates the process.

ある。The present invention forms a transparent electrode for applying a driving voltage on a layer made of a dyeable material without using special photomasks or other microfabrication means to form a light-shielding film in the gaps between color filters. Using the transparent electrode as an anti-dyeing mask, the dyeable layer exposed in the gap between the transparent electrodes is colored, and then a color filter with a completely patterned pattern is formed on the transparent electrode to easily form a light-shielding film. It is something to do.

である。By using the transparent electrode for applying driving voltage during display as a dye-resistant layer for the underlying layer of dyeable material, the process becomes very simple, and there is no need for extra material for patterning the light-shielding material. This eliminates the need for photomasks and the like.

であり、本発明にはそのまま適用できる。In the present invention, the transparent electrode is used not only for applying driving voltage but also for closing.
It is used as an anti-dyeing layer when the underlying layer made of a dyeable material is selectively dyed only in the gap between the transparent electrodes to form a light-shielding film. For this reason, transparent electrodes must have the property of not being dyed. Fortunately, tin oxide, indium oxide, antimony oxide, etc., which are commonly used as transparent electrode materials, can be used with common dyes, such as acid dyes and basic dyes. Usually, dyes have no affinity with direct dyes and are hardly dyed, and can be applied to the present invention as they are.

These polymeric materials contain many functional groups that have a strong affinity for dyes, so they can be easily dyed using dyeing methods widely used in the textile industry. However, many polymer materials are thermally unstable, and in some cases, they may not be able to withstand heat treatment when forming transparent electrodes thereon. In such cases, a dye-free layer is desirable. Typical examples include porous oxides. In particular, alumite formed by anodizing aluminum has excellent dyeability, and dyed alumite is widely used industrially. The dyeing method for alumite is basically the same as that for fibers, and it can be easily dyed from a solution of acid dyes.

The color filters 24, 24', 24' can be formed on the top with high precision self-alignment, and when combined with the present invention, the formation of the light shielding film and color filter becomes a very simple process without using a special photomask. ,
