Abstract:
Amplitude of a data line is made small, thereby reducing power consumption. Included are a first transistor to which a first scan signal is supplied through a first scan line; a second transistor to which a second scan signal is supplied through a second scan line; a third transistor which is turned on or off depending on a first signal supplied from a current supply line through the first transistor and a second signal supplied from a data line through the second transistor; a pixel electrode; and a light-emitting element which emits light by driving current flowing between the pixel electrode and a counter electrode. The first signal cuts electrical connection between the current supply line and the pixel electrode through the third transistor, and the second signal makes the current supply line and the pixel electrode electrically connected through the third transistor.
