Abstract
A display device includes a display panel, a color separation element configured to disperse light from a light source and to emit, to the display panel, a plurality of rays of separated light with wavelengths different from each other, and an outer adhesive portion that bonds a side surface of the display panel and the color separation element to each other over an entire perimeter of the display panel.
Claims8
A display device comprising:
- a display panel including a plurality of pixels each having a color filter,
- a color separation element configured to disperse light from a light source and to emit, to the display panel, a plurality of rays of separated light with wavelengths different from each other;
- a light source emitting light and disposed under the color separation element;
- and
- an outer adhesive portion that bonds a side surface of the display panel and the color separation element to each other over an entire perimeter of the display panel,
- wherein
- the color separation element is larger than the display panel in plan view, and is disposed between the display panel and the light source, and
- the color separation element is configured to:
- separate the light emitted from the light source for each wavelength corresponding to a color of each color filter;
- and
- cause the separated light with the each wavelength corresponding to the color filter to enter and be transmitted through the color filter.

A method for manufacturing a display device, the method comprising:
- applying a first adhesive containing a gap member of a given size to a board surface of a display panel;
- sticking together a board surface of a color separation element and the board surface of the display panel to which the first adhesive has been applied, with the first adhesive between the board surfaces, the board surface of the color separation element dispersing light from a light source and emitting a plurality of rays of separated light with wavelengths different from each other;
- and
- applying a second adhesive to the color separation element and the display panel, which have been stuck to each other with the first adhesive, over an entire perimeter of the display panel from a side surface of the display panel to the color separation element, outside of the first adhesive in plan view, wherein
- the display panel includes a plurality of pixels each having a color filter,
- the color separation element is larger than the display panel in plan view, and is disposed between the display panel and the light source, and
- the color separation element is configured to:
- separate the light emitted from the light source for each wavelength corresponding to a color of each color filter;
- and
- cause the separated light with the each wavelength corresponding to the color filter to enter and be transmitted through the color filter.
