Abstract
A display apparatus includes a pixel having a first area emitting light and a second area transmitting light. A pixel circuit unit is in the first area and includes a thin film transistor. An inorganic insulation layer is in the second area. A first insulation layer covers the pixel circuit unit in the first area, and has an opening exposing the inorganic insulation layer in the second area. A first electrode is on the first insulation layer in the first area. The first electrode is electrically connected to the pixel circuit unit. A second insulation layer covers edges of the first electrode and is outside the opening formed in the first insulation layer. A second electrode is in the first area. An intermediate layer, including an emissive layer, is between the first electrode and the second electrode.
