DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display, a color filter substrate and a color filter member used for the same.

[0002]

2. Description of the Related Art In a liquid crystal display device, two electrode substrates each having an alignment film are arranged so that the alignment films face each other, and a liquid crystal layer is sandwiched between the two substrates. The two electrode substrates are adhered to each other by a sealing material and a sealing material arranged in a peripheral region, and a granular spacer or a photolithography method is formed between the two substrates to maintain a distance between the substrates. A spacer column made of a resin is disposed. When a liquid crystal display device performs color display, a colored layer made of red (R), green (G), and blue (B) is disposed on one of the substrates, and a substrate having a colored layer or a switching element as necessary. A transparent protective film made of resin is formed thereon.

In such a liquid crystal display device, printing is caused by materials such as a sealing material, a sealing material, a spacer material, a protective layer material, and a colored layer member which are in direct contact with the liquid crystal layer or the alignment film. Irregularity, durability (reliability)
In some cases, display unevenness such as unevenness occurring after the test occurred. An object of the present invention is to prevent display unevenness or the like caused by such a member that comes into contact with a liquid crystal layer or an alignment film.

[0004]

According to the present invention, an alkyl acid, a phenylcarboxylic acid, a phenylcarboxylic acid derivative contained in a seal, a sealing material, a spacer, a colored layer, and the like are provided.
The total content or extraction amount of phenylenedicarboxylic acid, phenylenedicarboxylic acid derivative, alkylamine, aniline, aniline derivative, phenylenediamine, phenylenediamine derivative, phenyleneaminecarboxylic acid, phenyleneaminecarboxylic acid derivative, and alkylimide in a predetermined range By controlling, uneven alignment and burning can be prevented.

[0005] The alignment unevenness and printing are performed by using a liquid crystal display device having a liquid crystal layer sandwiched between a sealing material, a sealing material, a spacer material, a colored layer, and other alkyl acids, phenylcarboxylic acids, and phenylcarboxylic acid derivatives. , Phenylenedicarboxylic acid, phenylenedicarboxylic acid derivative, alkylamine, aniline, aniline derivative, phenylenediamine, phenylenediamine derivative, phenyleneaminecarboxylic acid, phenyleneaminecarboxylic acid derivative, alkylimide, phthalimide derivative, cyanobenzene derivative,
It is thought that organic impurities such as dicyanobenzene derivatives seep into the liquid crystal or are absorbed by the alignment film, and the sealing material, sealing material, spacer material, coloring layer material, etc. come into direct contact with the liquid crystal layer or the alignment film. It is considered to occur when there is an area. This is because impurities contained in a sealing material, a sealing material, a spacer material, a coloring layer material, etc., seep into a liquid crystal layer or an alignment film involved in a display region and are eluted into the liquid crystal layer. The cause is presumed to be the adsorption of the impurities on the alignment film. Further, it was found that these impurities were particularly contained in the green layer and the black layer among the colored layers. That is, the pigments that are usually used as a part of the green coloring material or the black coloring material of the color filter of the liquid crystal display device are G7 and G36 pigments, which contain a large amount of impurities as described above. Furthermore, constituent components such as a dispersant and a polymer component when dispersing this in a colored paste also contain many impurities. It is also conceivable that unexpected impurities may be mixed in the resist forming step of mixing and dispersing them. Further, it is considered that the above-mentioned pigments and dispersants are decomposed at high temperatures, by contact with alkalis, or by exposure to ultraviolet rays to generate the above-mentioned organic impurities. As described above, it has been found that the green layer generates more impurities in the liquid crystal layer and the alignment film layer than other colors, for example, the red layer and the blue layer. The above-mentioned organic impurities can be reduced by purifying the pigment or dispersant used for the green colored layer forming resist and selecting these and the materials to be used.

In arriving at the present invention, the inventors of the present invention have considered the effects on display when various organic and inorganic substances are mixed in a liquid crystal cell and the refining of materials used (particularly, defective display in printing). A simple evaluation experiment was performed. The experiment was performed as follows.

In a liquid crystal cell, alignment films are applied to an array substrate having switching elements and pixel electrodes on a glass substrate and an opposing substrate having an opposing electrode on the glass substrate, respectively. A TN cell structure in which substrates were arranged and a liquid crystal layer was sandwiched between the substrates was provided. In the experiment, two types of alignment film materials and two types of liquid crystal materials were used, and various organic and inorganic substances were adhered to the alignment film as attachments in each case, and uneven baking and durability (reliability) tests were performed. Display unevenness such as generated unevenness was evaluated. Table 1 shows the evaluation results.
