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.

Abstract: Provided are a liquid crystal panel which has good visibility and in which a decrease in the display quality is sufficiently suppressed, and a head mounted display and a liquid crystal display device using the same. The liquid crystal panel includes a liquid crystal layer, a spacer, and a light-shielding section between a first substrate a second substrate facing the first substrate. The light-shielding section includes column-direction light-shielding sections arranged in a column direction and shielding parts between the pixels aligned in a row direction from light, and row-direction light-shielding sections arranged in the row direction and shielding parts between the pixels aligned in the column direction from light. The row-direction light-shielding sections include one that includes a first light-shielding section including an arrangement region of the spacer and a second light-shielding section adjacent to the first light-shielding section in the column direction.
