A solid-state image sensor filter includes: a light-incident surface on which light is incident; an infrared filter located on a side of a photoelectric conversion element on which the light-incident surface is disposed; and a barrier layer located on a side of the infrared filter on which the light-incident surface is disposed, the barrier layer being provided to suppress transmission of an oxidation source to thereby prevent the infrared filter from being oxidized.

Solid-state image sensor filter and solid-state image sensor

A photosensitive green composition for a color filter of a solid-state imaging element, contains a colorant (A), a binder resin (B), a photopolymerization initiator (C), a photopolymerizable monomer (D), an ultraviolet absorber (E), and a monofunctional thiol (F), wherein the colorant (A) contains C.I. Pigment Green 36 and/or C.I. Pigment Green 58.

Coloring composition for solid-state imaging element

A reflection-type display panel includes a substrate, a pixel electrode formed on the substrate, a reflection display layer formed on the pixel electrode, a transparent electrode formed on the reflection display layer, and a color filter formed on the transparent electrode and including an ink fixation layer. The color filter has colored portions formed on the ink fixation layer such that the colored portions correspond respectively to driving units of the pixel electrode, and the colored portions each include a coloring composition including a pigment and a binder resin such that a weight ratio of the pigment to the binder resin in each of the colored portions is in a range of from 1:9 to 5:5.

Reflection-type display panel and method of producing the same

An electrophoretic reflective color display has a color filter on an electrophoretic display layer displaying black and white. A colored portion and a non-colored portion are provided in a pixel of the color filter layer, and the colored portion has a hue defined by specified values of chromaticity coordinates (a*, b*), measured with transmitted light using a D65 light source, in a chromaticity diagram of the L*a*b* color system.

Reflective color display

An article having a color pattern formed therein comprises a substrate, banks on the substrate, and a colored layer provided between the banks. The colored layer has a thickness of 80-120% of an average thickness thereof. In addition, the banks have an ink repelling agent or the upper apex portion of the banks has ink repelling ability.

Color filter

An alkali-developable photosensitive color composition containing a binder resin, a fluorine-containing copolymer, a photopolymerization initiator, a colorant, and a solvent. A photopolymerizable unsaturated compound is used as the binder resin. The photopolymerizable unsaturated compound is obtained by adding (B) an unsaturated monobasic acid to (A) a polyfunctional epoxy resin to form (C) an epoxy adduct and allowing the epoxy adduct (C) and (D) a polybasic acid anhydride to react with each other.
