An absorption type near-infrared filter comprising a first multilayer film, a second multilayer film, and an absorption film, wherein in the ultraviolet band, the difference of between the wavelength with the transmittance at 80% of the absorbing film and the wavelength with the reflectivity at 80% of the first multilayer film falls in the range between 25 nm and 37 nm, the difference of between the wavelength with the transmittance at 50% of the absorbing film and the wavelength with the reflectivity at 50% of the first multilayer film falls in the range between 6 nm and 14 nm, and the difference of between the wavelength with the transmittance at 20% of the absorbing film and the wavelength with the reflectivity at 20% of the first multilayer film falls in the range between −6 nm and 2.5 nm.

Absorption type near infrared filter

An absorption type near-infrared filter comprising a first multilayer film, a second multilayer film, and an absorption film comprising an infrared absorbing dye with a weight percentage between 1% and 3%, wherein in the infrared band, the difference between the wavelength with the transmittance at 80% of the absorption film and the wavelength with the reflectivity at 80% of the first multilayer film ranges between 130 nm and 145 nm; the difference between the wavelength with the transmittance at 50% of the absorption film and the wavelength with the reflectivity at 50% of the first multilayer film ranges between 75 nm and 90 nm; the difference between the wavelength with the transmittance at 20% of the absorption film and the wavelength with the reflectivity at 20% of the first multilayer film ranges between 25 nm and 45 nm.

A concave display including a first substrate, a second substrate, a display medium, a color filter layer, an optical film and an active device layer is provided. The second substrate is disposed opposite to the first substrate. The display medium is disposed between the first substrate and the second substrate. The color filter layer is disposed on the first substrate. The active device layer is disposed on the first substrate or the second substrate. The optical film is disposed on the first substrate. The optical film is further away from the display medium than the color filter. The optical film includes a base material and optical microstructures embedded in the base material, wherein a refractive index of each of the optical microstructures is smaller than a refractive index of the base material.
