The display substrate includes: a pixel in the display area; a gate driver at the non-display area and including a gate and data wiring; an organic layer on the gate and data wiring; a column spacer on the organic layer; a connection portion connected to the gate and data wiring at contact holes respectively exposing the gate and data wiring; and a protective layer on the connection portion. In a top plan view, the protective layer has a same shape as a shape of the connection portion. The opposing substrate includes a black matrix at the display area to define a pixel area of the pixel and at the non-display area to define the display area and the non-display area.
