Abstract: A detection apparatus includes a first substrate, a first electrode, a plurality of second electrodes, a detection controller, and a second electrode controller. The first electrode is disposed on the first substrate. The second electrodes have an area smaller than the area of the first electrode and overlap the first electrode. The detection controller is coupled to the first electrode and detects a detection signal corresponding to a capacitance change in the first electrode. The second electrode controller supplies, to some of second electrodes in the second electrodes, a guard signal for suppressing a capacitance change in overlapping areas of the first electrode overlapping the respective second electrodes.

Abstract: A display apparatus includes a basement, a display functional layer, a first electrode, a guard electrode, and a detection controller. The basement has a first surface and a second surface opposite to the first surface. The display functional layer is arranged on the side of the second surface of the basement. The first electrode is arranged between the basement and the display functional layer and detects an object in contact with or in proximity to the first surface. The guard electrode is arranged between the first electrode and the basement and supplied with a guard signal. The guard signal suppresses a change in capacitance generated between the first electrode and the guard electrode. The detection controller is a controller to which a signal based on a change in capacitance of the first electrode is output from the first electrode.

Abstract: According to an aspect, a liquid crystal display device includes: a first substrate; a second substrate; a liquid crystal layer between the first and second substrates; pixels each including sub-pixels corresponding to different color areas; a first electrode in each sub-pixel; and a second electrode facing the first electrode. The first electrode includes an electrode base portion extending in a first direction; and a plurality of comb tooth portions extending in a second direction from the electrode base portion. A slit pitch of a sub-pixel in one color area and a slit pitch of a sub-pixel in the other color area of at least two color areas out of different color areas are different in size, each slit pitch corresponding to a gap between the comb tooth portions adjacent to each other.
