Title:
液晶表示装置
Document Type and Number:
Japanese Patent JP5890847
Kind Code:
B2
Abstract:
This liquid crystal display device (100) includes: a first substrate (10) including a pixel electrode (11); a second substrate (20) including a counter electrode (21); and a vertical alignment liquid crystal layer (30). At least one liquid crystal domain with axisymmetric alignment is produced when a voltage is applied between the pixel electrode and the counter electrode in each pixel. The second substrate further includes an alignment controlling projection which induces liquid crystal molecules (31) in the liquid crystal domain to get aligned axisymmetrically and a plurality of columnar spacers (24), which includes a first columnar spacer (24m) and a second columnar spacer (24s) which is lower than the first columnar spacer. The pixel electrode has a length of 35 μm or less as measured along its shorter sides. In at least some of the pixels, the second columnar spacer functions as the alignment controlling projection. And the height (Hs) of the second columnar spacer is 75% to 92% of the height (Hm) of the first columnar spacer.
