1. An in-cell touch panel comprising:
a first substrate;
a plurality of color filters formed on the first substrate;
a transmitter electrode formed on one of a layer on an opposite side of a touch surface with respect to the plurality of color filters and a layer closer to a touch surface side with respect to the plurality of color filters;
a receiver electrode formed on the other one of the layer on the opposite side of the touch surface with respect to the plurality of color filters and the layer closer to the touch surface side with respect to the plurality of color filters; and
a second substrate disposed to face the first substrate and including a pixel electrode disposed on the second substrate,
wherein the plurality of color filters includes a blue color filter, a red color filter, and a green color filter,
both the transmitter electrode and the receiver electrode are disposed in a part of a portion overlapping the blue color filter in a plan view,
at least one of the transmitter electrode and the receiver electrode includes a first gap portion formed in at least a part of a portion overlapping the green color filter in the plan view, and
the first gap portion is not formed in the part of the portion overlapping the blue color filter in the plan view.
