FIGS. 2B, 2C, and 2D illustrate array structures of sub-pixels included in at least one pixel according to various embodiments of the disclosure. For convenience of description, the color filter CF1 covering the first to fourth sub-pixels PD1, PD2, PD3, and PD4 is omitted, and the first to fourth sub-pixels PD1, PD2, PD3, and PD4 and the first to third micro lenses ML1, ML2, and ML3 are illustrated in FIGS. 2B to 2D.
Referring to FIG. 2B, the first to fourth unit sub-pixels PD1, PD2, PD3, and PD4 included in the at least one pixel 210 may be arranged in the shape of a rectangle. In this case, the third sub-pixel PD3 and the fourth sub-pixel PD4 may be disposed to be contiguous to each other in a transverse direction as illustrated in FIG. 2B. Referring to FIG. 2C, the third sub-pixel PD3 and the fourth sub-pixel PD4 may be disposed to be contiguous to each other in a longitudinal direction. Referring to FIG. 2D, the third sub-pixel PD3 and the fourth sub-pixel PD4 may be disposed to be contiguous to each other in a diagonal direction.
