Abstract

The invention discloses an array substrate and a display panel. The array substrate comprises a plurality of scanning lines, a plurality of data lines and a plurality of sub-pixel units; each sub-pixel unit comprises a thin film transistor and a pixel electrode, and each thin film transistor comprises a grid electrode connected with the corresponding scanning line, a source electrode connected with the corresponding data line and a drain electrode connected with the corresponding pixel electrode; and in the direction parallel to the plane of the array substrate, the source electrode comprises two branch parts located in the sub-pixel units, the drain electrode is connected with the pixel electrode through a connecting hole, and the drain electrode and the connecting hole are arranged in the range defined by the two branch parts. According to the invention, the drain electrode and the connecting hole are arranged in the range defined by the two branch parts of the source electrode, so that the area occupied by the drain electrode is reduced, and the problem of bright spots or poor vertical line shape of a display panel caused by short circuit of the drain electrode and the data lines is avoided.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to an array substrate and a display panel. Background technique [0002] Liquid crystal display panels are widely used due to their advantages such as wide viewing angle, high brightness, high contrast ratio, low power consumption, and light and thin volume. Among them, the active thin film transistor display panel (Thin Film Transistor-LCD, TFT-LCD) has been rapidly developed and widely used in recent years. Most of the liquid crystal display panels currently on the market are backlight liquid crystal display panels, which include a liquid crystal display panel and a backlight module. Generally, a liquid crystal display panel consists of a color filter substrate (Color Filter, CF), an array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), a liquid crystal (Liquid Crystal, LC) sandwiched between the color filter substrate and the array substrate...
