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.
