Abstract: A method for manufacturing a display panel is provided, the method including forming a semiconductor pattern on a base layer, applying at least one insulation layer on the semiconductor pattern, and applying a control electrode on the insulation layer so as to overlap at least a portion of the semiconductor pattern. The applying of the control electrode includes depositing molybdenum to form a preliminary electrode layer, forming a photoresist pattern on the preliminary electrode layer, and applying an etching gas to dry-etch the preliminary electrode layer. In an embodiment, in the dry-etching, the etching gas may include a nitrogen trifluoride gas, an oxygen gas, and a chlorine gas. Accordingly, it is possible to implement a manufacturing process of an eco-friendly display panel while increasing the yield and reliability of the display panel manufacturing process.

Abstract: A display device is disclosed that includes a base layer, a light-emitting element, and a pixel circuit. The pixel circuit includes a first transistor, and the first transistor includes a metal oxide semiconductor pattern, a first gate having a plurality of conductive layers, and a gate insulation pattern. The uppermost layer among the plurality of conductive layers is divided into a first part adjacent to a drain region, a second part adjacent to a source region, and a third part between the first part and the second part. An upper surface of each of the first part and the second part may form a step with an upper surface of the third part. A sum of the widths of the upper surfaces of the first part and the second part may be smaller than the width of the upper surface of the third part.

Abstract: A display device includes a display area, a pixel circuit area adjacent to the display area, and a functional module area between the display area and the pixel circuit area. An inorganic insulating layer is in the display area. A light phase compensation layer is in the functional module area and includes a same material as the inorganic insulating layer. A signal line is disposed in the functional module area, on the light phase compensation layer, and extends from the functional module area to the pixel circuit area. The organic insulating layer is on the inorganic insulating layer and extends from the display area to the functional module area to cover the signal line and the light phase compensation layer.
