first auxiliary pixels for displaying a first primary color, each of the first auxiliary pixels being provided with a first color filter for passing light of the first primary color;
second auxiliary pixels for displaying a second primary color, each of the second auxiliary pixels being provided with a second color filter for passing light of the second primary color;
third auxiliary pixels for displaying a third primary color, each of the third auxiliary pixels being provided with a third color filter for passing light of the third primary color;
fourth auxiliary pixels for displaying a fourth color that is not the first primary color, not the second primary color, and not the third primary color; and
light shielding disposed only on peripheral edges of the fourth auxiliary pixels and not overlapping central portions of the fourth auxiliary pixels,
wherein,
the light shielding being disposed along at least one of boundary regions between the first auxiliary pixels and fourth auxiliary pixels adjacent to the first auxiliary pixels, the second auxiliary pixels and fourth auxiliary pixels adjacent to the second auxiliary pixels, the third auxiliary pixels and fourth auxiliary pixels adjacent to the third auxiliary pixels, or adjacent fourth auxiliary pixels, and
the light shielding is not disposed in boundary regions between the first auxiliary pixels and second auxiliary pixels adjacent to the first auxiliary pixels, the second auxiliary pixels and third auxiliary pixels adjacent to the second auxiliary pixels, or the third auxiliary pixels and first auxiliary pixels adjacent to the first auxiliary pixels.
2. The image display apparatus according to claim 1 , wherein the first primary color is red, the second primary color is green, the third primary color is blue.
3. The image display apparatus according to claim 1 , wherein:
the first, second, third and fourth auxiliary pixels are disposed in a first direction, and
the light shielding of the fourth auxiliary pixels is disposed along at least one of the boundary regions, which extend along a second direction crossing the first direction, of the auxiliary pixels.
4. The image display apparatus according to claim 1 , wherein opposing two sides of peripheries of each of the fourth auxiliary pixels are surrounded by the light shielding.
5. The image display apparatus according to claim 1 , wherein:
the first auxiliary pixels, the second auxiliary pixels, the third auxiliary pixels, and the fourth auxiliary pixels are arranged in a first direction,
the fourth auxiliary pixels are aligned in a second direction crossing the first direction, and
at least one side of peripheries along the second direction of each of the fourth auxiliary pixels is provided with the light shielding.
6. An image display apparatus comprising an image display panel, the image display panel including:
first auxiliary pixels for displaying a first primary color, each of the first auxiliary pixels being provided with a first color filter for passing light of the first primary color;
second auxiliary pixels for displaying a second primary color, each of the second auxiliary pixels being provided with a second color filter for passing light of the second primary color;
third auxiliary pixels for displaying a third primary color, each of the third auxiliary pixels being provided with a third color filter for passing light of the third primary color; and
fourth auxiliary pixels for displaying a fourth color that is not the first primary color, not the second primary color, and not the third primary color,
wherein,
light shielding that does not overlap central portions of the fourth auxiliary pixels is disposed along peripheral edges of the fourth auxiliary pixels in at least one of boundary regions between the first auxiliary pixels and fourth auxiliary pixels adjacent to the first auxiliary pixels, the second auxiliary pixels and fourth auxiliary pixels adjacent to the second auxiliary pixels, the third auxiliary pixels and fourth auxiliary pixels adjacent to the third auxiliary pixels, or adjacent fourth auxiliary pixels,
the first color filter and the second color filter between one of the first auxiliary pixels and one of the second auxiliary pixels are overlapped by the light shielding,
the second color filter and the third color filter between one of the second auxiliary pixels and one of the third auxiliary pixels are overlapped by the light shielding, and
the third color filter and the first color filter between one of the third auxiliary pixels and one of the first auxiliary pixels are overlapped by the light shielding.
7. The image display apparatus according to claim 6 , wherein the light shielding is provided in a layer different from a layer of the first color filter, second color filter, and third color filter.
