A touch panel embedded liquid crystal display device is disclosed. A touch panel embedded liquid crystal display device includes a first substrate having a plurality pixels defined in a matrix, a second substrate comprising first, second and third color filters to form a first, second and third color sub-pixels. A second substrate is opposed to the first substrate. A first photo-sensor is provided on the first substrate in a region corresponding to the first color sub-pixel and a second photo-sensor is provided on the first substrate in a region corresponding to the second or third color sub-pixel. A liquid crystal layer is provided between the first substrate and the second substrate, with a first planarization plate and a second planarization plate formed on rear surfaces of the first substrate and the second substrate, respectively, a wave guide formed on the second planarization plate, and a light emitting diode adjacent to the wave guide to emit and transmit a first color light to be sensed by one of the photo sensors.
