Problems solved by technology
Generally, the array substrate includes data lines and gate lines intersecting, and electrostatic discharge (Electro-Static Discharge, ESD) is prone to occur at the intersecting places between the data lines and the gate lines, so that the intersecting data lines and gate lines The place is damaged by static electricity
When ESD occurs at the intersection of the data line and the gate line, it will cause the display panel to fail to display normally, thereby affecting the display quality of the display device

The invention provides an array substrate and a display panel. The array substrate includes a substrate, the substrate includes a first surface, and the array substrate also includes a plurality of data lines and a plurality of gate lines, and the data lines and the gate lines are arranged on the first surface of the substrate. On one surface, the array substrate further includes a plurality of thin film transistors distributed in an array; the thin film transistor includes: a gate arranged in the middle of the first surface, and the gate is connected to the gate line; a gate insulating layer disposed on the gate and the first surface; an active layer disposed on the gate insulating layer, the active layer being at the intersection of the data line and the gate line The width of the active layer is the first dimension, and the width of the active layer at the point where the data line does not intersect the gate line is the second dimension; the source electrode and the drain electrode arranged on the active layer are spaced apart, so The source is connected to the data line; the first size is larger than the second size.
Description
technical field [0001] The invention relates to the display field, in particular to an array substrate and a display panel. Background technique [0002] With the advancement of technology, display devices such as flat panel displays have been more and more widely used. A thin film transistor array substrate, referred to as an array substrate, is a common component in a display device, and the quality of the array substrate directly affects the quality of the display device. Generally, the array substrate includes data lines and gate lines intersecting, and electrostatic discharge (Electro-Static Discharge, ESD) is prone to occur at the intersecting places between the data lines and the gate lines, so that the intersecting data lines and the gate lines The place is damaged by static electricity. When the ESD occurs at the intersection of the data lines and the gate lines, the display panel cannot display normally, thereby affecting the display quality of the display device...
