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.
