Array substrate and display device
First Claim
1. An array substrate, comprising gate lines, data lines, and a plurality of pixel units defined by intersecting the gate lines and the data lines, the gate lines, the data lines and the pixel units being formed on a substrate, wherein each pixel unit comprises a thin film transistor (TFT), in an overlapping area between an active layer and a source of the TFT, the active layer comprises at least two first tabs protruding beyond a gate of the TFT, the at least two first tabs are disposed on both sides of a central line of the active layer parallel to the gate line respectively and have a same width in a direction of gate line;
- the at least two first tabs are arranged in symmetry;
the farther from a gate driver side of the array substrate is, the width of the first tabs in the direction of gate line has an increasing tendency.

Abstract
Disclosed is an array substrate including gate lines (210), data lines (220) formed on a base substrate and a plurality of pixel units defined by intersecting the gate lines (210) and the data lines (220). Each pixel unit includes a TFT. In an overlapping area between an active layer (230) and a source (240) of the TFT, the active layer (230) includes at least two first tabs (231) beyond a gate (260) of the TFT which are located on both sides of a central line of the active layer (230) parallel to the gate line (210) respectively and the two first tabs (231) have a same width in a direction of gate line (210). The above-mentioned array substrate can guarantee that the gate-source capacitance is substantially identical to a predesigned capacitance even if the active layer experiences misalignment while being manufactured, thereby decreasing the error of the common electrode voltage Vcom. Further disclosed is a display device including the above-mentioned array substrate.
