SUBSTRATE FOR LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a substrate for a liquid crystal display device having a protrusion for liquid crystal alignment control having excellent electric characteristics and light-shielding properties without spoiling patterning characteristics and reliability.

SOLUTION: The protrusion 27 for alignment control is a cured product of a photosensitive resin composition containing an organic pigment and a lower part of the protrusion for alignment control has a relational form to follow a recessed part 28 on the lower side thereof. The organic pigment content is 5 to 70 wt.% to the cured product of the photosensitive resin composition. The cured product of the photosensitive resin composition has dielectric tangent of ≤0.015 in a driving frequency range. The cured product of the photosensitive resin composition has optical density per μm film thickness of ≥0.2. A colored pixel layer 23 is provided between the protrusion 27 for alignment control and one surface of the substrate 21.
