Abstract: The present disclosure provides a display apparatus and a method for manufacturing the same. The display apparatus includes: a self-luminous display module, a fingerprint identification module below the self-luminous display module, at least two light shield layers between the self-luminous display module and the fingerprint identification module, and a planarization layer correspondingly arranged on one side, facing the self-luminous display module, of each light shield layer. Each light shield layer includes a plurality of mutually-independent openings; openings of one of the at least two light shield layers and openings of another of the at least two light shield layers overlap in a direction perpendicular to the fingerprint identification module; the planarization layer between two adjacent light shield layers includes a groove; and the groove and the openings do not overlap in the direction perpendicular to the fingerprint identification module, and a light blocking part is arranged in the groove.

Abstract: A fingerprint identification module is provided. The fingerprint identification module includes: a base substrate, a first conductive layer, and a third conductive layer that are laminated sequentially. The first conductive layer includes a first signal line and a second signal line, wherein the first signal line extends along a first direction and is connected to a gate of a reset transistor in a pixel sensing circuit, and the second signal line extends along the first direction and is connected to a gate of a switch transistor in the pixel sensing circuit. The third conductive layer includes a first conductive portion configured to form a first electrode of a photodiode in the pixel sensing circuit, wherein an orthographic projection of the first conductive portion on the base substrate does not overlap with orthographic projections of the first signal line and the second signal line on the base substrate.
