According to one embodiment, a display device includes a light source unit, a light guide unit, a lens, and a light emitting layer. The light source unit emits light to the light guide unit. The lens concentrates the light emitted from the light source unit. The light guide unit guides the light concentrated by the lens toward the light emitting layer. The light guided by the light guide unit is transmitted to the light emission layer without any intervening prism layer.


According to one embodiment, a backlight device includes a frame formed of a sheet material, a first adhesive layer provided on one surface of the frame, a reflective sheet attached to the frame with the first adhesive layer, an optical member disposed on the reflective sheet in the frame, and a light source disposed in the frame and configured to emit light to the optical member. In at least a part of the frame, a width of the frame and a width of the first adhesive layer are equal to each other, and at least an external surface of the frame and an external surface of the first adhesive layer are flush with each other.

A display device includes plurality of light-emitting elements aligned on a TFT substrate in a formation of a matrix. The plurality of light-emitting elements each have a flat surface portion and including a light-emitting layer, an anode, and a cathode, an insulating layer formed on the TFT substrate and under the light emitting element, and a tilted metal surface provided on a peripheral area surrounding the flat surface portion of the light-emitting element and having a tilt angle with respect to the flat surface portion of the light-emitting element. The tilted metal surface is provided on a surface of a slope of a bank that is provided on the insulation layer, and a width of a cross-section of the bank becomes smaller as the cross section comes farther away from a surface of the TFT substrate. A counter substrate is placed on the TFT substrate.
