Abstract
A display panel includes pixel structures. Each pixel structure includes an active device, a pixel electrode, and a protective layer. The pixel electrode is electrically connected to the active device, wherein the pixel electrode has at least one block-shaped electrode. The protective layer is located below the pixel electrode and includes a recess main portion and recess branched portions. The width of the recess main portion is greater than 0 μm and equal to or less than 4 μm, and the recess branched portions are extended along at least four directions. The pixel electrode covers the recess main portion and the recess branched portions. The display panel includes at least one polarizer, wherein the direction of an adsorption axis of the polarizer is different from the four directions of extension of the recess branched portions.
