Abstract
A display device with a position detecting function includes: an optical position detecting device which includes a position detecting light source for alternately emitting position detecting infrared light having a light amount attenuated along a predetermined direction and position detecting infrared light having a light amount attenuated along a reverse direction of the predetermined direction, and a light receiving element for receiving the position detecting infrared light reflected by a target object inside a detection region, and which detects a position of the target object on the basis of a light amount detection result of the light receiving element; and an image creating device which includes an image display region of an electric optical panel in a region overlapped with the detection region, wherein the light receiving element is constituted by a semiconductor element formed on the electric optical panel.
