Abstract

The present invention relates to a gray light-sensitive resin composition, a color filter manufactured by using the same and a display element comprising the same. The gray light-sensitive resin composition comprises a pigment dispersion composition, an alkali soluble resin, a photopolymerization compound, a photopolymerization initiator and a solvent. The pigment dispersion composition comprises more than selected from a red pigment, a green pigment, a cyan pigment, a yellow pigment and a purple pigment and a black pigment, and is characterized by when being formed as a curing film of which the thickness is 2.5 micrometers, having a transmissivity more than 30% and less than 75% at 460-530 nm spectral wavelengths, having a transmissivity more than 20% and less than 75% at 580-620 nm spectral wavelengths, and having a transmissivity less than 20% at 690-780 nm spectral wavelengths. The gray light-sensitive resin composition of the present invention has a very excellent anti-external light reflection effect, can substitute a polarizer in the display element, and solves the problems that the high chromatic (gray) reproducibility and machinability of the conventional gray light-sensitive resin composition are insufficient.

Description

technical field [0001] The present invention relates to a gray photosensitive resin composition, a color filter manufactured using the same, and a display element including the color filter. Background technique [0002] Recently, attention has been drawn to flexible display elements that can display images even when bent like paper by forming a display portion, wiring, etc. on a flexible substrate made of plastic such as a flexible material. [0003] The scope of application of flexible display elements is diverse, not only in computer monitors and televisions, but also in personal portable devices, in particular, organic light emitting display devices (Organic Light Emitting Display; OLED) and liquid crystal display devices (Liquid Crystal Display; LCD) does not require an additional light source, so a relatively thin thickness can be achieved, and in this regard, organic light-emitting elements are being actively studied for flexible display elements. [0004] On the oth...
