摘要:
A fingerprint recognition sensor according to an exemplary embodiment of the present invention includes: a photo sensor for sensing light that is diffuse-reflected from a finger of a user and incident on the photo sensor, or that is transmitted through the finger and incident on the photo sensor; a first matrix positioned on the photo sensor and including a first opening; a second matrix positioned on the first matrix and including a second opening; and a cover layer including one surface contacting the finger and positioned on the second matrix, wherein, from among light that is diffuse-reflected from the finger and incident on the cover layer or that is transmitted through the finger and incident on the cover layer, light having an angle, formed by a normal line on the one surface of the cover layer and a path of the light incident on the cover layer, that is greater than a critical angle, sequentially passes through the second opening and the first opening and is incident on the photo sensor.
