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.
