Abstract
A display device includes an infrared touch module, a back casing and a display panel. The infrared touch module includes a light guide member, a circuit board and an infrared transmitter. The circuit board is disposed on the light guide member and the infrared transmitter is disposed on an arrangement plane of the circuit board. The light guide member defines a touch plane and an angle is included between the arrangement plane and the touch plane, wherein the included angle is larger than 0 degree and smaller than or equal to 90 degrees. The back casing and the light guide member are combined with each other so that an accommodating space is formed between the light guide member and the back casing. The display panel is disposed in the accommodating space and has a display plane, wherein the display plane is substantially parallel to the touch plane.
