Abstract
In order to improve the light transmissivity above the transparent comb-teeth electrodes provided in an in-plane switching mode active matrix liquid crystal display unit, the liquid crystal gaps above the transparent comb-teeth electrodes are made larger than the liquid crystal gaps between the transparent comb-teeth electrodes.
Claims13
An in-plane switching mode active matrix liquid crystal display unit comprising:
- a first substrate including a plurality of scan lines, a plurality of common lines parallel with the scan lines, a plurality of data lines that cross the scan lines, and active elements near the cross portions of the data lines and the scan lines;
- a second substrate parallel with the first substrate;
- a liquid crystal layer between the first and second substrates;
- a plurality of transparent comb-teeth electrodes on the first substrate for applying electric fields to the liquid crystal layer;
- and
- first insulating patterns on the first substrate, the first insulating patterns being spaced from ends of each of said electrodes,
- wherein liquid crystal gaps above the transparent comb-teeth electrodes are approximately 1.0 μm to 1.5 μm larger than liquid crystal gaps between the transparent comb-teeth electrodes.
