Abstract:
The present invention relates to an optical fingerprint sensor which can comprise: a backlight unit for irradiating light; an uneven surface layer onto which the light from the backlight unit is irradiated; and a photosensor unit arranged between the backlight unit and the uneven surface layer so as to detect the light irradiated from the backlight unit and reflected from a user's fingerprint coming into contact with the uneven surface layer.
