Abstract
Official abstract text for this publication.
Disclosed herein is a display device including: a pixel array unit; and a driving unit; wherein the pixel array unit includes first scanning lines and second scanning lines in a form of rows, signal lines in a form of columns, and pixels in a form of a matrix, the pixels being disposed at parts where the first scanning lines and the signal lines intersect each other, each pixel includes a drive transistor of an N-channel type, a sampling transistor, a switching transistor, a retaining capacitance, and a light emitting element, the driving unit includes a write scanner for sequentially supplying a control signal to each first scanning line, a drive scanner for sequentially supplying a control signal to each second scanning line, and a signal selector for alternately supplying a signal potential as a video signal and a predetermined reference potential to each signal line.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device comprising: a switching transistor controllable to provide electrical connection and disconnection between an anode of a light emitting element and a terminal of an auxiliary capacitance, said terminal of the auxiliary capacitance being directly electrically connected to a terminal of a retaining capacitance and being directly electrically connected to a drain terminal of the switching transistor; a drive transistor controllable to provide…
