Abstract: Disclosed is a method of manufacturing a display panel. The method includes forming a lower layer on a base layer, forming a preliminary anode including a first initial layer and a second initial layer on the lower layer, patterning the preliminary anode so as to form an anode including a first layer and a second layer, forming an emission part, and forming a cathode. The patterning of the preliminary anode includes forming a photoresist layer, etching the first and second initial layers to form the first layer and the second layer, removing the photoresist layer, and first cleaning. At least a part of the lower layer exposed from the anode is removed during the removing of the photoresist layer or the first cleaning.

Abstract: A sputtering target includes a first target part and a second target part both including a metal oxide and adjacent to each other and a target dividing part disposed between a first target part and a second target part. The target dividing part includes a same metal element as a metal element included in a first target part and a second target part. Therefore, size and/or length of the sputtering target may be increased. Thus, efficiency of a manufacturing process of the sputtering target is improved and a manufacturing cost is reduced. In addition, even after a thin film is deposited on a target substrate using the sputtering target, stains caused by sputtering of non-uniform amounts of metal elements by location on the target substrate do not occur on a target substrate. In addition, the uniformity of a thin film deposited on a target substrate is secured by using the sputtering target. Thus, process quality of a sputtering process is improved.
