1. A light emitting device comprising:
a plurality of pixel circuits arranged to form a plurality of rows and a plurality of columns and each including a light emitting element;
a plurality of signal lines each extending in a column direction and configured to supply a pixel signal to a corresponding pixel circuit among the plurality of pixel circuits;
a plurality of row selection lines each extending in a row direction and configured to supply a row selection signal to a corresponding pixel circuit among the plurality of pixel circuits, the row selection signal indicating a row selected from the plurality of rows; and
a plurality of column selection lines each extending in the column direction and configured to supply a column selection signal to a corresponding pixel circuit among the plurality of pixel circuits, the column selection signal indicating a column selected from the plurality of columns,
wherein at least one of the plurality of pixel circuits includes a light emission control circuit configured to allow the light emitting element of a pixel circuit, among the plurality of pixel circuits, located on the row indicated by the row selection signal and on the column indicated by the column selection signal to emit light in a brightness according to the pixel signal that is being supplied to the pixel circuit, and
wherein the light emission control circuit allows the light emitting element of a pixel circuit, among the plurality of pixel circuits, located on the row indicated by the row selection signal and on a column that is not indicated by the column selection signal to emit light in a brightness according to the pixel signal supplied before the pixel signal that is being supplied to the pixel circuit.
