Document Type and Number:
Japanese Patent JP7118130
Kind Code:
B2
Abstract:
To provide a pixel circuit capable of suppressing a decrease in luminance due to leakage of a transistor without increasing the number of elements or with a minimum increase in the number of elements even if the number is increased.A pixel circuit is provided including a light-emitting element, a drive transistor configured to supply a current to the light-emitting element, a first reset transistor configured to set a potential of an anode of the light-emitting element to a predetermined potential, a first write transistor configured to control writing of a signal voltage at a gate node of the drive transistor, a holding capacitance having one end connected to the gate node of the drive transistor and configured to hold a threshold voltage of the drive transistor, and a second write transistor connected in series between the gate node of the drive transistor and the first write transistor.
