Abstract
A colored film has an uneven structure on a surface thereof, in which an average distance between adjacent projections in the uneven structure is equal to or shorter than 1,500 nm, a standard deviation of the distance between the adjacent projections is 10 to 300 nm, and 95.00% or more of the projections satisfy Formula (1), in Formula (1), h represents a height of the projections, and D represents an average distance between the adjacent projections, Formula (1) 3h/D≥1.0.
Claims12
A colored film comprising an uneven structure on a surface,
- wherein an average distance between adjacent projections in the uneven structure is equal to or shorter than 1,500 nm,
- a standard deviation of the distance between the adjacent projections is 10 to 300 nm,
- 95.0% or more of the projections satisfy Formula (1),
- Formula (1) 3h/D≥1.0,
- in Formula (1), h represents a height of the projections, and D represents the average distance between the adjacent projections,
- the uneven structure has projections that do not satisfy the requirement of Formula (1), and
- a density of the projections that do not satisfy the requirement of Formula (1) is 0.01 to 10/cm2.
