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 an emission area and a non-emission area. A light emitting element includes a first electrode, an emission layer on the first electrode, and a second electrode on the emission layer. A pixel defining layer includes a first opening defined therein and exposing the first electrode. A first encapsulation layer is on the second electrode to overlap the light emitting element. The first encapsulation layer includes a first inorganic layer on the second electrode and a second inorganic layer on the first inorganic layer. A top surface of the second electrode overlaps the first opening and includes at least one first stepped portion. A bottom surface of the second inorganic layer directly contacts a top surface of the first inorganic layer. At least one of the top surface of the first inorganic layer or a top surface of the second inorganic layer is a flat surface.
