Abstract
Official abstract text for this publication.
An object is to provide a display device that performs accurate display. A circuit is formed using a transistor that includes an oxide semiconductor and has a low off-state current. A precharge circuit or an inspection circuit is formed in addition to a pixel circuit. The off-state current is low because the oxide semiconductor is used. Thus, it is not likely that a signal or voltage is leaked in the precharge circuit or the inspection circuit to cause defective display. As a result, a display device that performs accurate display can be provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device comprising: a pixel portion including a plurality of pixels; and a circuit, wherein the circuit includes a plurality of first transistors, wherein each of the plurality of pixels includes a second transistor and a display element, wherein gates of the plurality of first transistors are electrically connected to each other, wherein at least one of first terminals of the plurality of first transistors is electrically connected to a f…
