1. A display device comprising:
a display panel including a pixel and a drive circuit configured to drive the pixel;
a light source device configured to emit emitted light toward the display panel;
a color separation element placed between the display panel and the light source device, the color separation element being configured to disperse the emitted light and to emit, to the pixel, a plurality of rays of separated light with wavelengths different from each other; and
a light-shielding member placed in the display panel, the light-shielding member being configured to block the emitted light heading toward the drive circuit, wherein
the display panel comprises a first substrate, a second substrate, and a liquid crystal layer, the second substrate being located on an opposite side of the color separation element across the first substrate, the liquid crystal layer being present between the first substrate and the second substrate,
the drive circuit is placed on a board surface of the first substrate facing the second substrate, and
the light-shielding member is at a position overlapping the drive circuit in plan view on the board surface of the first substrate facing the color separation element.
