Abstract

Embodiments may disclose an organic light-emitting display device including a first substrate including a pixel area emitting light in a first direction, and a transmittance area that is adjacent to the pixel area and transmits external light; a second substrate facing the first substrate and encapsulating a pixel on the first substrate; an optical pattern array on the first substrate or the second substrate to correspond to the transmittance area, the optical pattern array being configured to transmit or block external light depending on the transmittance area according to a coded pattern; and a sensor array corresponding to the optical pattern array, the sensor array being arranged in a second direction that is opposite to the first direction in which the light is emitted, the second array receiving the external light passing through the optical pattern array.
