Display apparatus having pixel electrodes arranged on a planarization layer
摘要
說明書
According to some aspects, a display apparatus includes a substrate, a first planarization layer, a first pixel electrode, a second pixel electrode, a third pixel electrode, a pixel definition layer, a first intermediate layer, a second intermediate layer, a third intermediate layer, and an opposite electrode. The substrate includes a first area corresponding to a first emission portion, a second area corresponding to a second emission portion, and a third area corresponding to a third emission portion. The first planarization layer is arranged over the substrate. The first planarization layer includes a first via hole, a second via hole, and a third via hole. The first pixel electrode is arranged on the first planarization layer and is electrically connected to a first pixel circuit through the first via hole. The second pixel electrode is arranged on the first planarization layer and is electrically connected to a second pixel circuit through the second via hole. The third pixel electrode is arranged on the first planarization layer and is electrically connected to a third pixel circuit through the third via hole. The pixel definition layer is arranged on the first pixel electrode, the second pixel electrode, and the third pixel electrode. The pixel definition layer includes a first opening exposing a central portion of the first pixel electrode, a second opening exposing a central portion of the second pixel electrode, and a third opening exposing a central portion of the third pixel electrode. The first intermediate layer is arranged on the first pixel electrode. The second intermediate layer is arranged on the second pixel electrode. The third intermediate layer is arranged on the third pixel electrode. The opposite electrode is arranged on the first intermediate layer, the second intermediate layer, and the third intermediate layer. A second distance defined as a shortest distance from an inner surface of the second opening to the second via hole is greater than a first distance defined as a shortest distance from an inner surface of the first opening to the first via hole.
