  • Patent number: 11057554
    Abstract: Disposing a functional device such as a camera on a display surface widens a frame. A display device (2) includes a display panel (DP) including a first substrate (5). The display panel has a transparent section (TS) from which display light does not go out and which has a partial region (5s) of the first substrate. In plan view, the transparent section which is larger than a pixel (PX) is disposed on an inner side of an edge of a display area (3) or is disposed to cut out the display area. The display panel has a back surface on which a functional device (FD) configured to perform at least one of light reception or light emission is disposed to overlap the transparent section.

  • Publication number: 20200174314
    Abstract: A polarizing plate includes: a polarizer; a hard coat layer; and a recess formed at an outer edge of the polarizing plate or a through hole bored through the polarizing plate in a thickness direction. At least the polarizer and the hard coat layer are stacked, and the hard coat layer is not formed in a stress concentration part, included in the edge at which the recess or the through hole is formed, in which stress concentrates in a case where a change in temperature of the polarizing plate is effected with the hard coat layer formed all over the polarizer.
