Abstract: A method of manufacturing a detection sensor is disclosed. The method includes forming a biometric information sensing layer including a transistor on a base layer, forming an initial optical pattern layer on the biometric information sensing layer, patterning the initial optical pattern layer to form a plurality of transmissive portions spaced apart from each other and having a first zeta potential, coating a light blocking material to form an initial light blocking portion that covers a side surface and an upper surface of the transmissive portions and has a second zeta potential different from the first zeta potential, and polishing the initial light blocking portion such that the upper surface of the transmissive portions is exposed to form a light blocking portion. The initial light blocking portion is polished by the abrasive, which has the first zeta potential, using a pad.
