Display device having through hole section for image acquisition and image display

A display device, comprising:

• a backlight module comprising a backlight section and a through hole section, wherein the backlight section surrounds at least a portion of the through hole section;
• a liquid crystal cell disposed on the backlight module;
• a light guide body disposed in the through hole section;
• a light-emitting unit disposed on a light incident surface of the light guide body;
• a camera unit disposed on a first surface of the light guide body;
• wherein the light guide body comprises:
• a main body comprising a first surface and a second surface, wherein the first surface is disposed away from the liquid crystal cell and corresponds to a hollow section of a first polarizer of the liquid crystal cell, and the first surface is configured to transmit light from an external environment toward a portion of the liquid crystal cell corresponding to the through hole section;
• and the second surface is disposed opposite to the first surface, and is configured to transmit light emitted from the light-emitting unit or the light from the external environment toward the portion of the liquid crystal cell corresponding to the through hole section;
• and
• a coupling portion connected to the main body and comprising at least one light incident surface, wherein the coupling portion is disposed correspondingly to a light-exiting surface of the light-emitting unit, and is configured to transmit the light emitted by the light-emitting unit.
