Liquid crystal display and manufacturing method thereof

Abstract

A liquid crystal display including a couple of substrates facing each other and pixel electrodes formed on inside surfaces of the couple of substrates, each of the pixel electrodes has gaps. A liquid crystal layer is sealed between the couple of substrates with the pixel electrodes formed and the gaps are alternately disposed to form a staggered arrangement between the pair of pixel electrodes. The liquid crystal layer has pre-tilt regions where liquid crystal molecules are tilted. In these regions, the spacing between adjacent pre-tilt regions is smaller than spacing in the substrate surface direction between the gap of a pixel electrode on one substrate and the gap of a pixel electrode on the other substrate.

AI Technical Summary

Benefits of technology

The present invention provides a method of manufacturing a liquid crystal display with improved response speed against voltage, while suppressing a drop in contrast. The method involves selectively imparting a pre-tilt angle to liquid crystal molecules in a region around the slits of the electrodes. By exposing the liquid crystal layer through a light shielding film with small openings, the pre-tilt angle can be efficiently imparted to the region with low response speed. The method does not require precise alignment between the mask for exposure and the pixel electrodes slits, and can be performed easily. The liquid crystal display made using this method has efficient response speed against voltage and suppressed contrast drop.

Problems solved by technology

This increases the luminance of the black display, leading to a drop in contrast.

However, in consideration of the spacing between the slits disposed in the upper and lower electrodes, it is extremely difficult to perform a limited exposure by selecting the pre-tilt region as described above.

This is because it is not easy to make precise alignment between the opening position of a mask for selective exposure and the slit position of the electrodes.
