Abstract
Provided is a fingerprint sensor using a microlens including the microlens changing a path of light reflected by a fingerprint structure, and an optical-TFT checking the fingerprint structure from the light whose path is changed. Since the microlens including the spherical lens to change the path of light is provided, the amount of light incident on the light measuring area can be maximized. Also, since the noise such as dispersed light is exhausted by the spherical lens outside the light measuring area, the effect by the noise can be minimized.
