Liquid crystal cell process for in-plane switching mode liquid crystal display device

Abstract

Liquid crystal cell process for in-plane switching mode liquid crystal display devices. A process for forming an in-plane switching liquid crystal display device includes: defining a first liquid crystal cell region having a first size and a second liquid crystal cell region having a second size on a first bare glass, wherein the first bare glass Above, the first longer side of the first liquid crystal cell area is arranged along the first direction, and the second longer side of the second liquid crystal cell area is arranged along the second direction; in the first and second liquid crystal cell areas of the first bare glass forming a plurality of array elements including a plurality of thin film transistors, a plurality of common electrodes and a plurality of pixel electrodes, wherein the common electrodes and pixel electrodes define a plurality of concentric annular holes; grinding the first array element having the plurality of array elements along a first grinding direction a bare glass; forming a color filter layer on a second bare glass in which a liquid crystal cell region corresponding in size to the first and second liquid crystal cell regions is defined; and in a direction opposite to the first grinding direction The second grinding direction grinds the second bare glass with the color filter.

Description

technical field [0001] The present invention relates to liquid crystal display devices. More specifically, it relates to a liquid crystal display device implementing in-plane switching (IPS), in which an electric field to be applied to liquid crystals is generated in a plane parallel to a substrate. Background technique [0002] Liquid crystal display devices use optical anisotropy and polarization properties of liquid crystal molecules to generate images. The elongated shapes of liquid crystals can be aligned to have an orientation along a specific direction. The alignment direction of the liquid crystals can be controlled by an applied electric field. In other words, when the applied electric field changes, the alignment of the liquid crystal molecules also changes. Due to the optical anisotropy of liquid crystals, the refraction of incident light depends on the alignment direction of liquid crystal molecules. Therefore, by appropriately controlling the electric field ...
