ABSTRACT:
A display apparatus including pixel circuits arranged in the row and column direction to form a display portion, the pixel circuit including a capacitor which holds an electric signal representing information, a driving transistor, a control terminal of which is connected to one end of the capacitor and which outputs driving current according to information held in the capacitor, a light emitting element which emits light with brightness according to current output from the driving transistor, and a switching element which opens and closes a current path from the driving transistor to the light emitting element, wherein a time period during which the switching element closes the current path is set to be the longest in the pixel circuit at the center of the display portion and to be gradually shorter according to the distance to the end side of the display portion.
