Display device

A display device, comprising:

• a light source apparatus, having a first light emitting surface;
• a rear light transmitting module disposed opposite the first light emitting surface, wherein the rear light transmitting module includes:
• a first transmitting layer, having a plurality of first prisms arranged side by side and respectively protruding toward the first light emitting surface, wherein two sides of each first prism respectively have a first gentle surface and a first steep surface arranged along an extension direction of the first prisms, and the first steep surface is closer to upright than the first gentle surface relative to the first light emitting surface;
• and
• a second transmitting layer, overlapped with the first transmitting layer on one side thereof opposite the first light emitting surface, wherein the second transmitting layer has a plurality of second prisms arranged side by side and protruding toward the first transmitting layer, in which two sides of each second prism respectively have a second gentle surface and a second steep surface arranged along an extension direction of the second prisms, and wherein the second steep surface is closer to upright than the second gentle surface relative to the first light emitting surface;
• and
• a display panel disposed on one side of the light source apparatus opposite the rear light transmitting module, the light source apparatus having a second light emitting surface opposite the first light emitting surface and facing the display panel,
• wherein a vertical projection range of the first prisms on the first light emitting surface is misaligned with a vertical projection range of the second prisms on the first light emitting surface.
