Display device

A display device, comprising:

• a first light source module, comprising a first light source and a first light guide plate, wherein the first light guide plate comprises a first light-incident surface and a first light-emitting surface connected to the first light-incident surface;
• a second light source module, comprising a second light source and a second light guide plate, wherein the second light guide plate comprises a second light-incident surface and a second light-emitting surface connected to the second light-incident surface;
• a display panel, disposed between the first light-emitting surface and the second light-emitting surface, wherein the first light-emitting surface and the second light-emitting surface face the display panel, wherein the first light source emits a first light beam into the first light guide plate through the first light-incident surface, and the first light beam is emitted from the first light-emitting surface and transmitted to the display panel, and the second light source emits a second light beam into the second light guide plate through the second light-incident surface, and the second light beam is emitted from the second light-emitting surface and transmitted to the display panel;
• and
• a transparent filling disposed between the first light guide plate and the display panel and between the second light guide plate and the display panel, wherein the transparent filling connects the display panel to the first light-emitting surface and the second light-emitting surface, wherein a refractive index of the transparent filling is smaller than refractive indices of the first light guide plate and the second light guide plate, and smaller than or equal to a refractive index of a surface material of the display panel.
