Abstract
A display device includes: a plurality of drive electrodes extending in a first direction and arranged side-by-side in a second direction with an inter-electrode slit in between; and a plurality of pixel electrodes arranged in matrix in the first and second directions. Each of the drive electrodes has one or more inner-electrode slits, and a center of the pixel electrode is located in the inter-electrode slit or in the inner-electrode slit.
Claims12
A display device, comprising:
- a plurality of drive electrodes extending, in a first direction, with a length larger than that of an effective display region, and arranged side-by-side in a second direction with an inter-electrode slit in between, each of the drive electrodes being supplied with a drive signal;
- a plurality of pixel electrodes arranged in a matrix in the first and second directions to face the drive electrodes, each of the pixel electrodes being supplied with an image signal;
- a gate driver allowing pixel electrodes in a pixel line in the first direction to be supplied with a scan signal;
- and
- a drive electrode driver allowing the drive electrodes to be supplied with the drive signal,
- wherein,
- the inter-electrode slit extends to pass over a center region of each of the pixel electrodes,
- each of the drive electrodes has a width in the second direction corresponding to a size in the second direction of two or more pixel electrodes, and has one or more inner-electrode slits extending in the first direction at least within the effective display region,
- each of the inner-electrode slit and the inter-electrode slit extends to pass over center regions of the pixel electrodes that belong to the pixel line in the first direction,
- when the scan signal from the gate driver is to be applied to a first pixel line located in a region corresponding to the inter-electrode slit, the drive electrode driver applies the drive signal to both of a couple of drive electrodes that are adjacent to each other with the inter-electrode slit in between, and
- when the scan signal is to be applied to a second pixel line located in a region other than a region corresponding to the inter-electrode slit, the drive electrode driver applies the drive signal to a single drive electrode corresponding to the second pixel line.
