Liquid crystal display device and manufacturing method thereof

Abstract

The application relates to a liquid crystal display device and a preparation method thereof. The liquid crystal display device comprises a first substrate, a second substrate opposite to the first substrate, a color filter layer located on a side of the first substrate close to the second substrate, a color filter layer located on a side of the color filter layer close to the second substrate The first transparent conductive layer, the light-shielding element array extending from the first transparent conductive layer toward the direction close to the second substrate, the second transparent conductive layer located on the side of the second substrate close to the light-shielding element array, and the first transparent conductive layer and the light-shielding element array. A liquid crystal layer between the second transparent conductive layer. The second transparent conductive layer includes a plurality of common electrodes, each of which includes a plurality of ring-shaped sub-electrodes, and each sub-electrode does not overlap with the projection of the light-shielding element array on the first substrate.

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...

Problems solved by technology

However, since the pixel circuit formed on the first substrate also includes a thin film transistor (TFT), a storage capacitor (Cst), etc., its structure is relatively complicated, and the process of forming a patterned pixel electrode on it is complicated and may affect other circuit structures. , affecting the performance stability of liquid crystal display devices
