Abstract
In a display device, an edge portion of a pixel electrode is modified. A valley is provided in an overcoat layer located below the pixel electrode. The edge portion of the pixel electrode is configured to be curved or bent onto the overcoat layer. As a result, the aperture ratio of the display device can be increased, and an image abnormality in the edge portion of the pixel electrode can be prevented.
