Abstract

The invention discloses an array substrate, a preparation method thereof, and a display panel, in order to solve the problem that in the array substrate prepared by the prior art, pixel electrodes and common electrodes composed of translucent metal film layers parallel to the base substrate reduce the backlight transmittance , A problem that affects the brightness of TFT-LCD. The array substrate includes a base substrate, a plurality of pixel units arranged on the upper surface of the base substrate, and the pixel units are arranged in an array on the base substrate; corresponding The first electrode groove and the second electrode groove of each pixel unit, the first electrode groove and the second electrode groove extend from the upper surface to the lower surface of the base substrate; the pixel unit It includes a pixel electrode and a common electrode, the pixel electrode is formed in the first electrode groove, and the common electrode is formed in the second electrode groove.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to an array substrate, a preparation method thereof, and a display panel. Background technique [0002] Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, no radiation, and relatively low manufacturing cost, and occupies a dominant position in the current flat panel display market. [0003] The main structure of TFT-LCD includes an array substrate and a color filter substrate that are boxed together and liquid crystals are sandwiched between them. On the array substrate, gate lines that provide scanning signals, data lines that provide data signals, and pixel electrodes that form pixel points are formed. . In order to realize the display function, it is also necessary to set a common electrode, so that when the power is applied, the liquid crystal will rotate under the action of the electric field formed by the c...
