Pixel structure of thin film transistor-liquid crystal display and manufacturing method thereof

Abstract

The invention discloses a pixel structure of a thin film transistor-liquid crystal display and relates to a TFT-LCD technology, which is provided aiming to solve the problems of poor display effect and complex process of the current TFT-LCD. The invention adopts the technical scheme that the pixel structure comprises a grid line and a data line, wherein the grid line and the data line are intercrossed to form a pixel area, the pixel area comprises at least one thin film transistor and a pixel electrode, the source electrode of the thin film transistor is formed at the bottom layer, an active layer and a drain electrode are arranged on the source electrode in sequence, the source electrode is connected with the data line and the drain electrode is connected with the pixel electrode; the grid is formed on the side surface of the active layer and is connected with the grid line; and the side surface of the active layer and the grid part opposite to the side surface of the active layer form a vertical current channel, i.e., a side grid channel is formed. The invention also discloses a manufacturing method of the pixel structure. The invention obviously enhances the current intensity of the TFT channel, improves the display effect of the TFT-LCD and improves the manufacturing efficiency of the pixel structure of the TFT-LCD.

Description

technical field [0001] The invention relates to thin film transistor liquid crystal display (TFT-LCD, Thin Film Transistor-Liquid Crystal Display) technology, in particular to a pixel structure of a thin film transistor liquid crystal display and a manufacturing method thereof. Background technique [0002] In recent years, TFT-LCD has dominated the current flat panel display market due to its advantages of small size, light weight, low power consumption and no radiation. The TFT-LCD display screen is composed of an array glass substrate and a color film glass substrate, and the liquid crystal material is sealed after vacuuming. The TFT-LCD display forms an array of hundreds of thousands to millions of pixels, and each pixel displays images through the control of TFT.
