Abstract
A display device including a display section having a plurality of pixel electrodes; and a plurality of drive electrodes extending in a first direction and arranged side-by-side in a second direction. Each of the drive electrodes has a width in the second direction corresponding to a size of the two or more pixel electrodes, and has one or more slits extending in the first direction.
Claims7
A display device with a touch detection function, comprising:
- a pixel substrate;
- an opposed substrate disposed to face the pixel substrate;
- a plurality of drive electrodes arranged side-by-side on the pixel substrate,
- a plurality of pixel electrodes facing the drive electrodes, the pixel electrodes being arranged in a matrix of a first direction and a second direction crossing the first direction;
- and
- an image signal line on the pixel substrate, the image signal line extending in the second direction and supplying the pixel electrodes with the image signal,
- wherein
- each of the drive electrodes serves as a common drive electrode for displaying image and also serves as a drive electrode for touch sensing,
- each of the drive electrodes has one or more inner-electrode slits,
- an inter-electrode slit is formed between the drive electrodes adjacent to each other,
- one of the one or more inner-electrode slits is discontinued by non-slit portions of the drive electrode,
- the non-slit portions at least partially covers the image signal line, and
- a width of the inner-electrode slit is 10 micrometers or less.
