Abstract: Related to is a gate on array. A circuit for testing a gate line of an array substrate includes: a test pad and a first switch unit which connects the test pad and the gate line and has an end connected to a control terminal. A voltage is applied to the control terminal to control activation and deactivation of the first switch unit. The gate line is in normal operation when the first switch unit is deactivated, and the test pad tests a signal of the gate line when the first switch unit is activated. In normal display, the first switch unit is deactivated, and the gate line is in normal operation. This can avoid influences of an additional load, which would otherwise cause abnormal display of a picture. In a manufacturing procedure, explosive wound caused by electrostatic discharge of the test pad can be prevented. When a display device cannot be lit, an external voltage can be introduced to activate the first switch unit, so as to detect a signal of the gate line.

Abstract: The present invention provides a manufacturing method of a color filter substrate, in which a layer of photoresist layer of a negative photoresist resin material is first formed on the color filter film layer; then, back side exposure is conducted on the photoresist layer from the underside of the backing plate so that a part of the photoresist layer that is adjacent to the backing plate gets cured for subsequently forming a planarization layer; afterwards, a mask is used to conduct front side exposure on the photoresist layer from the backing plate to form post spacers; and finally, the photoresist layer that has been subjected to exposure twice is subjected to development to remove a portion of the photoresist layer that has not been cured so as to form, simultaneously, a planarization layer and post spacers located on the planarization layer.
