Description of the Invention: [Technical Field] The present invention relates to a photosensitive resin constituent block (a liquid which is disposed in a plurality of divided vertical alignment modes: a liquid crystal alignment control convex formed using the composition [previously Technology] Generally, the Braun tube display device (CRT) is most large and heavy when compared with the display area before the image information of the image information is displayed on the side. Therefore, the display area is large. However, a liquid crystal display device (LCD) which is thin and loosely used is gradually shown. The liquid crystal display device is a structure in which two glass substrates are sealed with liquid crystal in their gaps. On the other side of the glass substrate, a transparent pixel electrode is formed, and a circuit for applying a voltage is formed at the same time. However, since the liquid crystal display device displays the above-mentioned junction, there is a problem that the viewing angle is narrow. Viewing angle, there are proposed IPS (Switching) mode, VA (Vertical Alignment; Vertical, etc.. But even in VA mode, display intermediate color The crystallizing system is oriented obliquely to the same direction, the viewing angle is also changed to form a convex I cell, and the block is used. The device is used, but it is often used in any field. Instead of the Braun tube, it is fixed in a conspicuous manner, and a multi-pixel electrode is formed on the glass substrate to form a multi-pixel electrode, and the polarizing plate is sandwiched and switched; in the case of the In Plane Alignment method, since the liquid is narrow. 5 200815915 Therefore, in order to eliminate the view angle of the VA method at the intermediate color tone, there is a proposal (see Patent Document 1) to disclose an MVA (Multi-domain Vertical Alignment Multi-domain VA) method. In this method, a mode control means is provided, and when the voltage is applied, the alignment direction of the liquid crystals in the oblique alignment can be different in the direction of the different domains within the image. The control means may be provided on at least one of the two substrates, and the one of the control means has a slope. Further, the vane turning control means is provided with a projection. [Problem to be Solved by the Invention] However, the protrusion of the category control means (liquid alignment agent) described in Patent Document 1 or the like is usually colorless. Therefore, at the protrusions, there is a problem that display unevenness occurs due to light reflection. In view of the above problems, an object of the present invention is to provide a photosensitive fat composition for forming a liquid crystal alignment control bump capable of preventing light reflection and maintaining a dielectric constant (hereinafter also referred to as "bump" ))); and providing liquid crystal alignment control bumps using the composition. [Means for Solving the Problems] In order to solve the above problems, the inventors of the present invention have focused on the fact that the liquid crystal alignment bumps absorb light and repeat the intensive research. As a result, it has been found that the above problem can be solved by adding an organic pigment to the photosensitive resin composition for forming a bump to reduce the number of crystal domains to a low crystal grain and to control the above-mentioned problems. this invention. More specifically. The present invention provides the following. The first invention of the present invention is a photosensitive resin composition for forming a photosensitive resin composition which is provided in a liquid crystal cell of a plurality of divided vertical alignment modes and used for controlling the alignment of the liquid crystal. It contains organic "pigment (C). Further, the second invention of the present invention is a liquid crystal alignment control bump formed of the photosensitive resin composition.功效 [Efficacy] According to the photosensitive resin composition of the present invention, since the photosensitive resin composition contains an organic pigment, the liquid crystal alignment control bump formed of the photosensitive resin composition of the present invention can absorb light and prevent light. Chaos reflection. Further, since an organic pigment is used, a bump having a low dielectric constant can be formed.

The photosensitive resin composition of the present invention which forms a bump for controlling the alignment of the liquid crystal contains an organic pigment. The photosensitive resin composition of the present invention can form colored bumps by containing an organic pigment. Therefore, the formed bumps can absorb light and prevent random reflection of light. Further, since the organic pigment is used as the pigment, the dielectric constant of the formed bump can be lowered, and the shape stability of the formed bump 7 200815915 can be improved.
