Pixel structure of liquid crystal display screen and manufacture method for same

Abstract

The invention provides a pixel structure of a liquid crystal display screen. The structure is characterized by comprising a substrate, a metal layer, a first insulating layer, a public electrode layer, a second insulating layer as well as first pixel electrode layer and a second pixel electrode layer, wherein the metal layer is disposed on the substrate; the first insulating layer is disposed on the metal layer; the public electrode layer is disposed on the first insulating layer and directly touches the first insulating layer; the second insulating layer is disposed on the public electrode layer; and the first pixel electrode layer and the second pixel electrode layer are disposed on the second insulating layer and located in the same pixel structure. According to the invention, production time can be reduced; production cost can be reduced; and a production yield rate can be increased.

Description

technical field [0001] This case relates to a pixel structure of a liquid crystal display and its manufacturing method, in particular to a pixel structure of a liquid crystal display with high transmittance and its manufacturing method. Background technique [0002] With the continuous, extensive, in-depth and rapid development of liquid crystal display technology, liquid crystal display (LCD) has almost overwhelmingly occupied all major display markets, such as monitors, mobile phones, televisions, notebook computers, tablet personal Computer (Tablet PC), Global Positioning System (GPS) device, portable video player, etc. [0003] In the liquid crystal display, the liquid crystal acts as a light valve, controlling light penetration and light blocking in each pixel and / or sub-pixel of the liquid crystal display during real-time display time. From the perspective of the control mechanism of the liquid crystal, the liquid crystal display can be divided into two types: vertica...

AI Technical Summary

Problems solved by technology

As the resolution specification of the display screen is increasing day by day, the area of ​​each pixel and / or sub-pixel is getting smaller and smaller. In order to increase the aperture ratio of the pixel and / or sub-pixel, each pixel And / or the design and arrangement of the lines required by the sub-pixel in its limited area can only strive for the space for line configuration from the vertical direction of the substrate, so multiple photomasks are used to complete the required layer by layer. lines, but it also increases the number of photomasks used and the number of production procedures
