Color filter and electro-optical device
View Patent ↗A color filter ( 200 ) comprises pixels ( 13 ) separated from each other by partitions ( 14 ) formed on a substrate ( 12 ) so as to have a plurality of color elements of ink. Dummy pixels ( 13 ′) are formed outside the area in which the pixels ( 13 ) are formed. The amount of ink applied to each of said pixels and the amount of ink applied to each of said dummy pixels are substantially equal. A protective film ( 21 ) covering said pixels ( 13 ) is formed so as to also cover said dummy pixels ( 13 ′).
1. A color filter, comprising:
a plurality of pixels which are separated from each other by partitions formed on a formation area of a substrate, said pixels including a first coloring layer having an amount of coloring material; and
a plurality of dummy pixels separated from each other by the partitions, said dummy pixels including a second coloring layer having an amount of coloring material substantially the same as the amount of coloring material of the first coloring layer, the pixels being active display elements that contribute to an image display and having light transmittance characteristics that are substantially uniform among each of said pixels, and the dummy pixels being inactive elements in the contributions to the image display.
2. The color filter according to claim 1 , said dummy pixels being formed in an area outside an area in which said pixels are formed, and the amount of coloring material of each of said pixels are formed, and the amount of coloring material of each of said dummy pixels being substantially the same as the amount of coloring material of each of said pixels.
3. The color filter according to claim 2 , each of said dummy pixels being formed with an aperture portion smaller than an aperture portion of each of said pixels.
4. The color filter according to claim 2 , the amount of coloring material of said pixels and the amount of coloring material of said dummy pixels being substantially the same per unit of said substrate.
5. The color filter according to claim 1 , said dummy pixels being formed in an area outside an area in which said pixels are formed, and further comprising a protective film being formed so as to cover said pixels and said dummy pixels.
6. The color filter according to claim 5 , each of said dummy pixels being formed with an aperture portion smaller than an aperture portion of said pixels.
7. The color filter according to claim 5 , said protective film being formed so as to also cover the area outside the formation area of said partitions.
8. The color filter according to claim 5 , said protective film being formed so as to adhere to an exposed area of the substrate outside the formation area of said partitions.
9. An electro-optical device comprising a color filter according to claim 1 .
10. The electro-optical device according to claim 9 , further comprising a liquid crystal layer which selectively transmits light to said color filter.
11. The electro-optical device according to claim 9 , further comprising a discharge display portion which selectively transmits light to said color filter.
12. Electronic equipment comprising the electro-optical device of claim 9 .
13. A color filter, comprising:
pixels which are separated from each other by partitions formed on a formation area of a substrate so as to comprise a plurality of color elements of ink, the light transmittance characteristics in each pixel being substantially uniform among each of said pixels, said partitions including an inorganic shielding layer and an organic bank layer formed on top of the shielding layer, and an outermost portion of said bank layer being formed extending outside an outermost portion of said shielding layer, and said bank layer being in contact with said substrate.
