Abstract: An in-cell touch panel device includes a first substrate, a plurality of color filters formed on a layer on an opposite side of a touch surface with respect to the first substrate, a transmitter electrode formed on a layer on an opposite side of the touch surface with respect to the plurality of color filters, a receiver electrode formed on a layer closer to the touch surface side with respect to the plurality of color filters, and a second substrate, a pixel electrode being disposed on the second substrate. The transmitter electrode includes a gap portion formed in a portion overlapping a space between adjacent ones of the plurality of color filters in a plan view.

Abstract: An in-cell touch panel device includes a first substrate, a plurality of color filters formed on an upper layer with respect to the first substrate and including a green color filter, a transmitter electrode formed on an upper layer with respect to the plurality of color filters, a receiver electrode formed on a lower layer with respect to the plurality of color filters, and a second substrate including a pixel electrode disposed on the second substrate. The transmitter electrode includes a gap portion formed in a portion overlapping the receiver electrode in a plan view and in a portion overlapping the green color filter in a plan view.

Abstract: A display device includes a display panel and a control unit. The display panel includes a first substrate, a light modulation layer configured to switch between transmissive display and non-transmissive display, and a second substrate in this order, and further includes an optical sensor configured to detect a luminance of light incident from a first space located on one main surface side of the display panel and from a second space located on the other main surface side of the display panel. The control unit calculates, based on the luminance, a relationship between brightness of the first space and brightness of the second space as a numerical value and switches display of the light modulation layer based on the numerical value.
