Abstract: A light-emitting device has improved impact resistance over conventional configurations. Such a light-emitting device includes a display panel layer, a housing layer, an impact absorbing layer adjacent the housing layer, a metal layer that is disposed between the impact absorbing layer and the display panel layer and that is deformable during an impact on the light-emitting device, and a compliant layer that is disposed between the metal layer and the display panel layer that enables a shape of the display panel layer to be maintained when the metal layer is deformed. Due to a compliance or low stiffness of the compliant layer, a permanent deformation of the metal layer due to an impact or device shape change is not discernibly transferred into the shape of the display panel layer, and the shape of the display panel layer is essentially maintained so that an impact or shape change does not adversely affect display performance.

Abstract: A liquid crystal display device according to an aspect of the disclosure includes a liquid crystal panel including an element substrate, a counter substrate facing the element substrate, a liquid crystal layer sandwiched between the element substrate and the counter substrate, an incident-side linear polarizing plate arranged on a light-incident side of the liquid crystal layer, and an emission-side linear polarizing plate arranged on a light-emission side of the liquid crystal layer. Each of the element substrate and the counter substrate uses a resin film as base material. A plurality of insulating films are formed on the base material. A contact hole is formed in the plurality of insulating films, the contact hole being rectangular in plan view. Either a long side or a short side of the contact hole is parallel with an absorption axis of the incident-side linear polarizing plate or the emission-side linear polarizing plate.
