摘要： A display apparatus includes a timing controller, a data driver and a display panel. The data driver generates a positive polarity data voltage and a negative polarity data voltage based on image data compensated by the timing controller. The display panel includes a first pixel driven based on the positive polarity voltage and a second pixel driven based on the negative polarity voltage. The display panel receives a storage voltage applied to the first pixel and the second pixel. The timing controller compensates the image data when a variation on a level of the storage voltage occurs. The compensation shifts a level of the first data voltage from a first normal level to a first compensation level in a direction, and shifts a level of the second data voltage from a second normal level to a second compensation level in the same direction.

摘要： A display device includes pixels connected to gate lines and first and second data lines, dummy members extending in a first direction and disposed between adjacent pixels in a second direction crossing the first direction, and color filters extending in the second direction and overlapping pixels arranged in the second direction and disposed on the dummy members. A height of the color filters in step difference areas is larger than a height of the color filters in peripheral areas near the step difference areas. The step difference areas correspond to areas of the color filters in which the dummy members are disposed.
