Abstract

The invention relates to a liquid crystal display device and a preparation method thereof. The liquid crystal display device comprises a first substrate, a second substrate, a colored filter layer, afirst transparent conductive layer, a light-shielding element array, a second transparent conductive layer, and a liquid crystal layer, wherein the second substrate is opposite to the first substrate,the colored filter layer is located on the side, near the second substrate, of the first substrate, the first transparent conductive layer is located on the side, near the second substrate, of the colored filter layer, the light shielding element array extends in the direction from the first transparent conductive layer to the second substrate, the second transparent conductive layer is located on the side, near the light-shielding element array, of the second substrate, and the liquid crystal layer is located between the first transparent conductive layer and the second transparent conductive layer. The second transparent conductive layer includes a plurality of common electrodes, each common electrode includes a plurality of annular sub-electrodes, and the projections, on the first substrate, of the sub-electrodes and the light-shielding element array are not overlapped with one another.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a liquid crystal display device and a preparation method thereof. Background technique [0002] Liquid crystal display device is a flat and ultra-thin display device, which is composed of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays consume very little power, making them favored by engineers for electronic devices that run on batteries. Its main principle is to stimulate liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube. [0003] The working principle of liquid crystal display: Liquid crystal is a special substance between solid and liquid. It is an organic compound, which is liquid under normal conditions, but its molecular arrangement is as regular as solid crystal, so it is named liquid crystal. , Its othe...
