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.

Abstract: A display panel includes a base layer, and a light emitting element layer having a plurality of light emitting regions spaced apart from each other and a non-light emitting region. The light emitting element layer includes a first electrode, a pixel-defining film, a hole transport region, a light emitting layer to correspond to the plurality of light emitting regions, an electron transport region, and a second electrode. The electron transport region integrally overlaps the plurality of light emitting regions and the non-light emitting region, and the hole transport region does not overlap at least a portion of the non-light emitting region.
