Abstract: The present disclosure provides a gate driver on array (GOA) circuit, where the GOA circuit includes a GOA driving chip, a GOA driving signal line, an array substrate test chip, a test signal line, and a GOA protecting circuit. The GOA driving chip is used to generate a scan driving signal. The GOA driving signal line is used to transmit the scan driving signal to a corresponding scan line. The array substrate test chip is used to generate an array substrate test signal. The test signal line is used to transmit the array substrate test signal to the corresponding scan line. The GOA protecting circuit is arranged between the GOA driving signal line and the test signal line.

Abstract: A color film substrate, a manufacturing method thereof and a display device are provided, which relates to the field of display technology. The color film substrate includes a substrate, on which a display area and a non-display area are defined, wherein the non-display area is arranged at the peripheral of the display area; a first shading layer with a first conductivity arranged on the non-display area; and a second shading layer with a second conductivity arranged on one side of the non-display area that is away from the display area, wherein the second shading layer is arranged at the peripheral of the first shading layer and surrounds the first shading layer, the second conductivity is less than the first conductivity. In this way, the problem that the color film substrate is damaged by the static electricity could be solved, thereby improving the anti-static electricity ability of the color film substrate.
