The first grid unit CU1 and the second grid unit CU2 of the first emission area group have a first arrangement. In each column arranged as an n×n matrix, the first grid unit CU1 and the second grid unit CU2 are alternately arranged. When the first grid unit of the odd-numbered column is the first grid unit CU1, the first grid unit of the even-numbered column may be the second grid unit CU2.

This is done because the first opening OP-MR, the second opening OP-MB and the third opening OP-MG correspond one-to-one to the first emission area PXA-R and the second emission area PXA-B and the third emission area PXA-G.

Referring to FIG. 7D , two second connection parts CP2 connect two second sensing parts SP2 spaced apart from each other. The first to fourth connection areas CNT-A1 to CNT-A4 are provided between the two second connection parts CP2 and the two second sensing parts SP2.

When the first grid unit of the odd-numbered column is the second grid unit CU2, the first grid unit of the even-numbered column may be the first grid unit CU1.

As shown in FIG. 7F , the first grid unit in the first column 1stL of the second emission area group may be the second grid unit CU2, and the nth grid unit in the first column 1stL may be the second grid unit CU2. The first grid unit of the n-th column n-thL of the second emission area group may be the second grid unit CU2, and the n-th grid unit of the n-th column n-thL may be the second grid unit CU2.
