Patent ID: 8873018

Claim:
A display substrate comprising: a substrate comprising: a first pixel area including a first light-blocking region, a second pixel area adjacent to the first pixel area and including a second light-blocking region; and a thin film transistor in each of the first and second light-blocking regions; an insulating layer in the first and second light-blocking regions; a black matrix pattern layer on the insulating layer; a first column spacer which is in the first light-blocking region, protrudes directly from the black matrix pattern layer, and is spaced apart from the thin film transistor of the first light-blocking region in a plan view; and a second column spacer which is in the second light-blocking region, protrudes directly from the black matrix pattern layer, and is spaced apart from the thin film transistor of the second light-blocking region in the plan view, wherein a height of a top surface of the first column spacer is different from a height of a top surface of the second column spacer, the heights taken with respect to the substrate.
