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.
