Abstract

A high-definition and high-resolution display apparatus is provided. A conductive film, a first layer, and a first sacrificial layer are formed. The first layer and the first sacrificial layer are processed to expose part of the conductive film. A second layer and a second sacrificial layer are formed over the first sacrificial layer and the conductive film. The second layer and the second sacrificial layer are processed to expose part of the conductive film. The conductive film is processed to form a first pixel electrode overlapping with the first sacrificial layer and a second pixel electrode overlapping with the second sacrificial layer. Two insulating films covering at least a side surface of the first pixel electrode, a side surface of the second pixel electrode, a side surface of the first layer, a side surface of the second layer, a side surface and a top surface of the first sacrificial layer, and a side surface and atop surface of the second sacrificial layer are formed. The two insulating films are processed to form a sidewall covering at least the side surface of the first pixel electrode and the side surface of the first layer. The first sacrificial layer and the second sacrificial layer are removed. A common electrode is formed over the first layer and the second layer.
