Abstract
Input displays are provided. A representative input display comprises a first substrate, a second substrate, a liquid crystal layer, a photo sensor, a color filter, and a light-shielding element. The liquid crystal layer accommodated in a liquid crystal space is sandwiched between transparent first and second substrates, comprising a first substrate side and a second substrate side. The photo sensor overlies the first substrate side. The color filter disposed in the liquid crystal space, over the photo sensor. The color filter comprises a first opening exposing portions of the photo sensor. The light-shielding element is disposed alongside portions of a periphery of the photo sensor.
