PHOTOSENSITIVE RESIN COMPOSITION AND BUMP FOR CONTROLLING LIQUID CRYSTAL ALIGNMENT USING THE SAME

摘要

A photosensitive resin composition is provided to prevent diffused reflection of lights and form a bump for controlling liquid crystal alignment having a low dielectric constant. A photosensitive resin composition is placed within a liquid crystal cell of a plurally divided vertical alignment mode and forms a bump for controlling alignment of liquid crystals. The composition contains (A) a photopolymerizable compound, (B) a photopolymerization initiator, and (C) an organic pigment. The organic pigment is contained in an amount of 10-60% by mass based on the total solid components except a solvent. The bump for controlling liquid crystal alignment has an OD value of 0.6 or more at a film thickness of 1 micron, and a dielectric constant of 7 or less.
