DISPLAY DEVICE AND OPTICAL INPUTTING DEVICE

摘要

Disclosed is a display device. According to one embodiment of the present invention, the display device comprises: a light sensor arranged between the upper and lower substrates; a polarizing plate arranged on the upper substrate; and a first phase difference layer arranged on the polarizing plate. Light of elliptic polarization is λ/4 phase difference converted and reaches the light sensor through the first phase difference layer and polarizing plate.
