Title:
Display device
Document Type and Number:
Japanese Patent JP6188755
Kind Code:
B2
Abstract:
A display panel for displaying an image is provided with a plurality of pixels arranged in a matrix. Each pixel includes one or more units each including a purality of subunits. Each subunit includes a transistor in which an oxide semiconductor layer which is provided so as to overlap a gate electrode with a gate insulating layer interposed therebetween, a pixel electrode which drives liquid crystal connected to a source or a drain of the transistor, a counter electrode which is provided so as to face the pixel electrode, and a liquid crystal layer provided between the pixel electrode and the counter electrode. In the display panel, a transistor whose off current is lower than 10zA/μm at room termperature per micrometer of the channel width and off current of the transistor at 85° C. can be lower than 100zA/μm per micrometer in the channel width.
