Image display apparatus

1. 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;

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 shieldings disposed only on a peripheral edge of each of the fourth auxiliary pixels,

wherein,

the first auxiliary pixels, the second auxiliary pixels, the third auxiliary pixels, and the fourth auxiliary pixels are arranged in a two-dimensional plane, and

the light shieldings of the fourth auxiliary pixels are disposed along at least one of boundaries of the 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 third auxiliary pixels are disposed next to the fourth auxiliary pixels in the first direction.

4. The image display apparatus according to claim 3 , wherein:

the third auxiliary pixels are disposed along both of two sides of the fourth auxiliary pixels in a first direction, and

the first auxiliary pixels are disposed along both of two sides of the fourth auxiliary pixels in a second direction crossing the first direction.

5. The image display apparatus according to claim 1 , wherein:

the third auxiliary pixels are disposed diagonally with respect to the fourth auxiliary pixels, and

corners of the light shielding facing diagonally to the third auxiliary pixels are cut off.

6. The image display apparatus according to claim 1 , wherein

the first, second, third and fourth auxiliary pixels are disposed in a first direction,

the first auxiliary pixels are disposed along a side of the fourth auxiliary pixels in a second direction crossing the first direction.
