Abstract

A pixel structure, including a first semiconductor layer, a first active layer, a second semiconductor layer, a second active layer, a third semiconductor layer, and an electrode layer that are sequentially stacked, is provided. A first portion of the electrode layer is electrically connected to a first portion of the first semiconductor layer through a first opening of a first portion of the third semiconductor layer, a first opening of a first portion of the second active layer, a first opening of a first portion of the second semiconductor layer, and a first opening of a first portion of the first active layer. A second portion of the electrode layer is electrically connected to a second portion of the second semiconductor layer through a second opening of a second portion of the third semiconductor layer and a second opening of a second portion of the second active layer.
