US 2026/0090221 A1 · DISPLAY DEVICE

Abstract

A display device according to one embodiment includes a substrate including a display area and a non-display area adjacent to the display area. A first light-blocking layer is on the substrate. An active layer including a semiconductor area of a first transistor is on the first light-blocking layer, and a gate layer including a gate electrode of the first transistor is on the active layer. A source metal layer is on the gate layer and includes an anode connection electrode directly connected to the active layer to receive a driving current from the first transistor. A pixel electrode is on the source metal layer and directly connected to the anode connection electrode. A light-emitting layer is on the pixel electrode, and a common electrode is on the light-emitting layer. This structure supports efficient electrical connectivity and a simplified manufacturing process.
