Abstract: An OLED display device capable of improving picture quality by turning off an OLED element regardless of a charging time and input data of each subpixel is discussed. A reference voltage supplied to a reference line is supplied to an OLED element during at least one OLED off time after a light-emitting time and before a charging time according to control of a scan gate line and a sense gate line to turn off the OLED element. The reference voltage is lower than a threshold voltage of the OLED element.

Abstract: An organic light-emitting display panel can improve the color purity and color gamut by reducing optical interference between adjacent pixel areas.A black bank layer is disposed on a planarization layer, such that it is possible to suppress light emitted from an organic emission layer from being reflected via various paths to be scattered to adjacent pixel areas. In addition, the black bank layer comes in contact with a color filter layer via holes formed in the planarization layer to thereby reduce optical interference between adjacent pixel areas.In this manner, the color purity and color gamut of displayed images can be improved, and a display device with excellent image quality can be implemented.

Abstract: A display apparatus in which each unit pixel includes four sub-pixels is provided. The four sub-pixels of each unit pixel may sequentially receive a data line through single data line. Two sub-pixels disposed on a side of the data line may be connected to a reference voltage supply line by a reference connecting line intersecting the data line. Two sub-pixels disposed another side of the data line may be connected to the data line by a data connection line intersecting the reference voltage supply line. An intersection region of the reference connection line and the data line may have the same area as an intersection region of the data connection line and the reference voltage supply line. Thus, in the display apparatus, the variation in the charging rate due to the parasitic capacitance difference of the data connection line and the reference connection line may be reduced.
