Abstract
A color filter includes: a substrate that transmits light; and a colored layer being formed by an ink jet ink, the colored layer being arranged on a lattice point which is a virtual point in a plurality of virtual lattice patterns arranged on the substrate with a first pitch in a first direction and a second pitch in a second direction, the colored layer being separated in the first direction and the second direction.
Claims4
A color filter comprising:
- a substrate that transmits light;
- and
- a colored layer being formed by an ink jet ink, the colored layer being arranged on a virtual lattice point in a plurality of virtual lattice patterns arranged on the substrate with a first pitch in a first direction and a second pitch in a second direction,
- the colored layer being separated in the first direction and the second direction,
- wherein, in each row of the plurality of the virtual lattice patterns arranged in the first direction, when a maximum value is denoted by δmax and a minimum value is denoted by δmin in a positional deviation amount in the first direction between a center of the colored layer and the virtual lattice point, and a value obtained by averaging δmax−δmin in the virtual lattice patterns arranged in the first direction is defined as a colored layer positional deviation range E, the colored layer positional deviation range E is 1 μm to 10 μm,
- wherein, in each column of the plurality of the virtual lattice patterns arranged in the second direction, a position of the center of the colored layer in the first direction changes periodically with respect to the virtual lattice point,
- wherein the colored layer is configured with a plurality of unit colored layers, each of the unit colored layers is formed of a different type of ink, and positions of the unit colored layers are different in at least one of the first direction and second direction,
- wherein the plurality of the unit colored layers are respectively arranged on a plurality of virtual lattice points at positions different from each other in the virtual lattice patterns, and
- wherein, in each column of the plurality of the virtual lattice patterns, a position of the center of each of the unit colored layers in the first direction changes periodically with respect to each of the virtual lattice points.
