Abstract: A display apparatus includes a first substrate, a color filter, a gap maintaining pattern, a column spacer, and a blocking dam. The first substrate includes a display area and a peripheral area surrounding the display area. The color filter is disposed in the display area. The gap maintaining pattern is disposed in the peripheral area in a same layer as the color filter. The column spacer is disposed on the color filter. The blocking dam is disposed in a same layer as the column spacer and overlaps the gap maintaining pattern. The difference between the gap of the first and second substrates in the display area and the gap of the first and second substrates in the peripheral area may be decreased.

Abstract: A display substrate includes a base substrate, a switching element disposed on the base substrate a first layer disposed on the switching element, a first electrode disposed on the first layer, an insulation layer disposed on the first electrode, and a spacer disposed on the contact hole of the insulation layer. The switching element includes a gate electrode, a source electrode, and a drain electrode. A contact hole is defined in the insulation layer to partially exposing expose a portion of the first electrode.
