Abstract
There is provided a display device having a configuration suitable for increasing a screen size and reducing a thickness while ensuring adequate strength. The display device includes: a frame structure having a plurality of extrusion molded members coupled to one another; a display panel; and an intermediate member attached to the frame structure and holding the display panel.
Claims12
A display device, comprising:
- a frame structure having a plurality of extrusion molded members coupled to one another, the frame structure including a first beam and a second beam both extending in a horizontal direction, and a first pillar and a second pillar both extending in a vertical direction and joining both ends of the first beam and the second beam, wherein each of the first pillar and the second pillar are joined to both ends of the first beam and the second beam by respective L-shaped metal fittings;
- a display panel;
- an intermediate member attached to the frame structure and holding the display panel, the intermediate member having a substrate, apart from the display panel, extending along an outer edge of the display panel, and a plurality of pieces disposed along a longitudinal direction of the substrate and held by the substrate to set respective relative positions, each of the plurality of pieces including an abutment surface abutting the end surface of the display panel;
- and
- a surface light emitting unit comprising a plurality of light emitting elements arranged on a surface of the surface light emitting unit,
- wherein the display panel is a transmissive liquid crystal display panel having a display surface that displays an image, a back surface on a side opposite to the display surface, and an end surface that joins the display surface and the back surface, and
- the surface light emitting unit is disposed inside the frame structure with the surface of the surface light emitting unit facing the back surface of the display panel so that the light from the light emitting elements is applied directly from the surface of the surface light emitting unit toward the back surface of the display panel.
