Abstract
A display device includes a substrate having an active area and a non-active area; a plurality of first subpixels arranged in the active area; and a plurality of second subpixels arranged adjacent to a boundary area between the active area and the non-active area, wherein the first and second subpixels have storage capacitors that have different capacitance values from each other, so that visibility of the stepped shape generated in the boundary area can be eliminated.
Claims18
A display device comprising:
- a substrate having an active area and a non-active area;
- a plurality of first subpixels arranged in the active area;
- and
- a plurality of second subpixels arranged in the active area in close proximity to a boundary area between the active area and the non-active area, wherein the second subpixels are disposed closer to the boundary area than the first subpixels,
- wherein the first subpixels have a rectangular shape emission area in a plan view and the subpixels have a non-rectangular shape emission area in a plan view, and
- wherein each of the first subpixels includes a first storage capacitor with a first capacitance, each of the second subpixels includes a second storage capacitor with a second capacitance, and the first capacitance and the second capacitance are related based on a proportion associated with the rectangular shape emission area and the non-rectangular shape emission area.
