Abstract:
A light emitting device includes pixel circuits arranged to form rows and columns and each including a light emitting element, signal lines each extending in a column direction and configured to supply a pixel signal to the pixel circuits, row selection lines each extending in a row direction and configured to supply a row selection signal to the pixel circuits, and column selection lines each extending in the column direction and configured to supply a column selection signal to the pixel circuits. At least one of the pixel circuits includes a light emission control circuit configured to allow the light emitting element of a pixel circuit indicated by the row selection signal and the column selection signal to emit light in a brightness according to the pixel signal that is being supplied to the pixel circuit.
