Abstract

The invention relates to a pixel structure which is arranged on a baseplate and electrically connected with a scan line and a data line. The pixel structure comprises an active element, a lower capacitor electrode, an insulation layer and a pixel electrode. The active element is arranged on the baseplate, wherein, the active element is provided with a grid, a source electrode and a drain electrode, and the active element is electrically connected with the scan line and the data line. The lower capacitor electrode and the grid are separately arranged on the baseplate. The insulation layer covers the active element and the lower capacitor electrode, wherein, the insulation layer consists of a single film layer. The pixel electrode is electrically connected with the active element, and at least partial pixel electrode extends to the insulation layer on the upper part of the lower capacitor electrode.

Description

technical field [0001] The invention relates to a pixel and a liquid crystal display panel, and in particular to a pixel structure with a storage capacitor and an active element array substrate. Background technique [0002] Liquid crystal displays have the advantages of high image quality, small size, light weight, low voltage drive, low power consumption, and wide application range. Therefore, they have replaced cathode ray tubes (Cathode Ray Tube, CRT) and become the mainstream of the new generation of displays. Generally speaking, a liquid crystal display panel is mainly composed of an active element array substrate, a color filter substrate and a liquid crystal layer. [0003] More specifically, the active element array substrate is composed of a plurality of thin film transistors arranged in an array and pixel electrodes corresponding to each thin film transistor, wherein the thin film transistors are used as switching elements of the liquid crystal display unit. In a...
