Embodiment Construction

[0044] The array substrate provided by the embodiment of the present invention is suitable for various display types of liquid crystal display devices. Liquid crystal display devices use electric fields to control light transmittance to display images. According to the direction of the electric field that drives the liquid crystal, liquid crystal display devices are roughly classified into a vertical electric field drive type and a horizontal electric field drive type. The vertical electric field drive type liquid crystal display device is provided with a common electrode and a pixel electrode facing each other on the upper and lower substrates, and a vertical electric field is formed between the common electrode and the pixel electrode to drive the liquid crystal, such as TN (Twist Nematic, twisted nematic) type, VA (Verical Alignment, multi-domain vertical alignment) type liquid crystal display device. The horizontal electric field drive type liquid crystal display device is...

Abstract

The present invention provides an array substrate, which includes: a first metal region located on the edge of the array substrate, electrically connected to a common electrode line or a common electrode; The second metal area is used for accessing a regulated voltage, and the regulated voltage is a fixed voltage; the first metal area and the second metal area form at least one capacitor. In the present invention, a capacitor is formed inside the liquid crystal panel, one electrode of the capacitor is connected to Vcom, and the other electrode of the capacitor is connected to another voltage (including grounding), thereby achieving the technical effect of obtaining a more stable pixel common electrode voltage.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular to an array substrate and a manufacturing method and a display device. Background technique [0002] Liquid crystal displays are currently commonly used flat panel displays. Among them, the Thin Film Transistor Liquid Crystal Display (TFT-LCD) is the mainstream product in the liquid crystal display. [0003] TFT-LCD occupies most of the market share in the field of small and medium size due to its low cost, high yield and good display effect. Although the TFT-LCD technology has matured day by day, the picture quality still needs to be continuously improved to meet the demanding needs of consumers. [0004] The existing liquid crystal display panel includes an array substrate, a color filter substrate, and liquid crystals arranged between the array substrate and the color filter substrate. In the liquid crystal display device, the Vcom voltage supplied to the array substrate is...
