Display panel, display device, and electronic instrument
Abstract:
A display panel includes, for each pixel, a self light emitting device and a pixel circuit driving the self light emitting device. The pixel circuit has a retention capacitor, a first transistor writing a voltage corresponding to a video signal in the retention capacitor, and a second transistor driving the self light emitting device based on the voltage of the retention capacitor, and the display panel has a light exit face discharging a light emitted from the self light emitting device to outside and also has a light blocking layer blocking an external light introduced from the light exit face to the first transistor.
