Abstract:
Disclosed is a method for manufacturing black matrix and spacer, which includes steps of: providing a base substrate and coating the base substrate with a black photoresist layer; coating a transparent photoresist layer on black photoresist layer; providing a multi-tone mask plate including a first light-transmitting area and a second light-transmitting area, in which the transparent photoresist layer and the black photoresist layer both include a first section aligning with first light-transmitting area and a second section aligning with second light-transmitting area; using the multi-tone mask plate to expose transparent photoresist layer and black photoresist layer, in which the transparent photoresist layer in the first section forms a main spacer, and the black photoresist layer in the first section forms a first black matrix, the transparent photoresist layer in the second section forms an auxiliary spacer, and the black photoresist layer in the second section forms a second black matrix.

Claim (Index 1):
A method for manufacturing black matrix and spacer, comprising the steps of:\n providing a base substrate and coating a black photoresist layer on the base substrate; coating a transparent photoresist layer on the black photoresist layer; providing a multi-tone mask plate including a first light-transmitting area and a second light-transmitting area, wherein a transmittance of the first light-transmitting area is larger than that of the second light-transmitting area, and both the transparent photoresist layer and the black photoresist layer include a first section and a second section respectively aligning with the first light-transmitting area and the second light-transmitting area; and exposing the transparent photoresist layer and the black photoresist layer by the multi-tone mask plate, wherein the transparent photoresist layer in the first section is used to form a main spacer, the black photoresist layer in the first section is used to form a first black matrix, and the main spacer is stacked upon the first black matrix, and wherein the photoresist layer in the second section is used to form an auxiliary spacer, the black photoresist layer in the second section is used to form a second black matrix, and the main spacer is stacked upon the second black matrix.
