The pixel island array and the micro-lens array are fixed with respect to and spaced apart from each other, and the micro-lens array includes plural micro-lenses. The pixel island array includes plural pixel islands in one-to-one correspondence with the plural micro-lenses, and each pixel island emits light to the corresponding micro-lens such that the light reach a predetermined viewing position after passing through the corresponding micro-lens. The plural pixel islands emit light of plural colors, and the filter layer includes plural filter portions in one-to-one correspondence with the plural pixel islands. Each filter portion is located between the corresponding pixel island and the corresponding micro-lens, and is close to the corresponding micro-lens.
