Problems solved by technology

[0009] In contrast, when a transparent electrode material is deposited on a colored layer having overhangs by vapor deposition or sputtering, it is difficult to deposit the transparent electrode material below the overhangs, so discontinuities are likely to occur in the transparent electrodes.
That is, in this case, poor electrical connection is likely to occur at the position below the overhanging body.

Embodiment Construction

[0042] Hereinafter, the photosensitive coloring composition which is one aspect of this invention is demonstrated.

[0043] The photosensitive coloring composition of 1 aspect of this invention is used for manufacture of the color filter contained in display devices, such as a liquid crystal display device and a solid-state imaging element, or electronic equipment, for example. This photosensitive coloring composition contains a resin (A), a pigment (B), an active energy ray polymerization initiator (C), an active energy ray curable monomer (D), and a solvent (E). Hereinafter, these components are demonstrated one by one.

[0044] "Resin (A)"

[0045] In the said photosensitive coloring composition, resin (A) contains vinyl resin (F) in the ratio of 50 weight% or more with respect to resin (A), Preferably it is 60 to 100 weight%. The vinyl resin (F) will be described in detail later.

[0046] The transmittance of the resin (A) in the entire wavelength region of 400 to 700 n...

Abstract

Disclosed is a photosensitive coloring composition which has excellent dispersion stability of a pigment and good reworkability, and is capable of forming a colored layer that has a good cross-sectional shape. The photosensitive coloring composition contains a resin (A), a pigment (B), an active energy ray polymerization initiator (C), an active energy ray-curable monomer (D) and a solvent (E). The resin (A) contains a vinyl resin (F) in an amount of not less than 50% by weight, and the vinyl resin (F) contains a constituent unit (a) having a carboxyl group in an amount of 2-50% by weight, a constituent unit (b) having one or more cyclic structures, which are selected from the group consisting of aromatic rings represented by general formula (1), aromatic rings represented by general formula (2), aliphatic rings represented by general formula (3) and aliphatic rings represented by general formula (4), in an amount of 2-50% by weight, and other constituent units (c) in an amount of 10-80% by weight. (In general formulae (1) and (2), R represents a hydrogen atom or an alkyl group having 1-20 carbon atoms, which may have a benzene ring.)

Description

technical field [0001] The present invention relates to a photosensitive coloring composition, for example, to a photosensitive coloring composition useful for forming a color filter used in a liquid crystal display device or a solid-state imaging device. Moreover, this invention relates to the color filter formed using this photosensitive coloring composition. Background technique [0002] A twisted nematic (TN) mode is a representative display mode employed by liquid crystal display devices. A transmissive liquid crystal display device employing a TN mode has a structure in which a liquid crystal layer is sandwiched between first and second polarizing plates. According to the TN mode, the liquid crystal layer, for example, makes the first linearly polarized light that has passed through the first polarizer enter the second polarizer as it is, or converts it into circularly polarized light or elliptically polarized light and then enters the second polarizer, or converts it...
