Pixels are disposed in the second area based on a second arrangement corresponding to a second pixel group in which at least one of the sub-pixels of the first pixel group is omitted. Pixels are disposed in at least a part of the third area based on the first arrangement. A light transmittance portion is disposed in another part of the third area.
