Abstract: An active matrix substrate includes: a support substrate; and a plurality of pixels located on the support substrate, in which each of the plurality of pixels includes: a thin film transistor; a first color filter layer; a contact hole provided in the first color filter layer; and a pixel electrode electrically coupled to the thin film transistor through the contact hole, and has a second color filter layer in the contact hole, the plurality of pixels include a first pixel, and in the first pixel, the first color filter layer transmits light in a first wavelength band and the second color filter layer transmits the light in the first wavelength band or transmits either the light in the first wavelength band or another light when a layer for transmitting the other light is provided around the contact hole.

Abstract: An active matrix substrate includes a substrate that is transparent, and a plurality of pixels positioned on the substrate. Each pixel includes a thin-film transistor (TFT) positioned on the substrate, a first color filter layer disposed on the substrate so as to cover the TFT, a contact hole being provided in the first color filter layer, a pixel electrode that is positioned on a bottom face and a side face of the contact hole, and on the first color filter layer, and that is electrically connected to the TFT via the contact hole, and a second color filter layer disposed within the contact hole.
