Abstract

A pixel structure including a substrate, a signal line, a plurality of pixel units and a light blocking pattern layer is provided. The signal line is disposed on the substrate and has opposing first and second sides. Two adjacent pixel units are disposed respectively on the first side and the second side of the signal line. Each pixel units includes an active device, a common electrode, an insulating layer, and a pixel electrode. The insulating layer is located on the common electrode. The pixel electrode is located on the insulating layer and is electrically connected to the active device. The pixel electrode includes an edge strip electrode and a plurality of extension electrodes. The extension electrodes respectively extend from the edge strip electrode toward the signal line. The light blocking pattern layer is located between two adjacent pixel units, and the light blocking pattern layer and the signal line overlap with each other.
