    Abstract: A method of manufacturing a display panel includes forming a circuit layer including a gate, a source, and a drain on a base substrate and forming a light emitting element layer on the circuit layer. The forming of the circuit layer includes sequentially forming a preliminary metal layer, a preliminary oxide layer comprising molybdenum and tantalum, and a preliminary capping layer which comprise a preliminary electrode layer, cleaning the preliminary electrode layer, forming a photoresist layer pattern on the preliminary electrode layer, etching the preliminary electrode layer, and removing the photoresist layer pattern. During the etching of the preliminary electrode layer, a ratio between a removal speed ER1 of the preliminary oxide layer and a removal speed ER2 of the preliminary metal layer satisfies Equation 1 to maintain a low reflection property 1≤ER2/ER1≤3.  [Equation 1]

    Abstract: A display device includes a substrate including a display area and a peripheral area outside the display area. A circuit unit is disposed in the display area and includes a semiconductor layer. An insulating layer is on the semiconductor layer. A conductive layer is connected to the semiconductor layer through a contact hole in the insulating layer. The conductive layer includes an underlayer including a metal nitride including a first metal. A display element is disposed on the circuit unit and includes a pixel electrode electrically connected to the conductive layer. A connection layer is disposed under the conductive layer. The connection layer corresponds to the contact hole and includes a second metal.
