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: An electronic device includes a first display panel including a first display surface, and a second display panel including a second display surface and configured to be disposed such that light emitted from the first display surface is incident on the second display surface. The first display panel is configured such that light emitted from the first display surface and incident on the second display surface includes a large amount of P-polarization components. The second display panel is a reflection-type display panel, and includes a polarizer disposed on the second display surface and configured to absorb S-polarization components of incident light.

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.
