摘要： A flat panel display device formed in a pentile structure is provided, which includes a pixel portion and a lighting tester. The pixel portion includes a first pixel column, a second pixel column and a third pixel column. In the first pixel column, first pixels for displaying a first color and second pixels for displaying a second color are alternately arranged in a direction the data lines. In the second pixel column, first and second pixels arranged in reverse order of the first pixel column in a direction parallel to the data lines. In the third pixel column, third pixels for displaying a third color are arranged in a direction parallel to the data lines. The lighting tester applies a first voltage to the first pixel column and applies a second voltage to the second pixel column during a first time period. The lighting tester applies the second voltage to the first pixel column and applies the first voltage to the second pixel column during a second time period.
