Abstract

When radiating light onto a liquid crystal composition containing a photosensitive material, the alignment of liquid crystal molecules is adjusted by applying a voltage to the liquid crystal composition layer, to achieve substantially orderly alignment of the liquid crystal molecules, or the alignment of the liquid crystal molecules is made uniform by adjusting the structure of the liquid crystal display device, or any display defect is driven out of the display area. When radiating light to the liquid crystal composition containing the photosensitive material, the alignment of the liquid crystal molecules can be adjusted so as to achieve substantially orderly alignment of the liquid crystal molecules, and the liquid crystal display device can thus be driven stably.

Claims (8)

1. A liquid crystal display device having a display area and a BM area formed outside said display area, comprising:

a first substrate including a thin film transistor;

a second substrate including a color filter resin layer; and

a liquid crystal composition containing a photopolymerizable or thermally polymerizable component placed in a cell gap between said first and second substrates;

wherein said photopolymerizable or thermally polymerizable component is polymerized so as to define a direction in which liquid crystal molecules tilt when a voltage is applied,

a thickness of said color filter resin layer in said BM area is larger than a thickness of said color filter resin layer in said display area,

said cell gap in said BM area is not larger than said cell gap in said display area, and

said liquid crystal composition is sandwiched between said first and second substrates throughout the entire BM area.
