摘要: Provided is an optical laminate having the following feature: when the optical laminate is used in an image display apparatus, the optical laminate can express a sufficient brightness, can express a satisfactory hue, and can achieve a cost reduction while suppressing a reflectance. The optical laminate of the present invention includes: a wavelength conversion layer; and an absorption layer arranged on one side of the wavelength conversion layer, wherein the absorption layer has an absorption peak in a wavelength band in a range of from 580 nm to 610 nm, and wherein the absorption layer contains a compound x represented by the general formula (I) or the general formula (II).

摘要: Described herein are embodiments of squarylium compounds for use as filters in light-emitting and/or display devices. One problem of known quarylium dyes is that strong nucleophiles can attack the electron-deficient cyclobutene ring which can lead to a loss of the dye's colour. Another potential drawback with squaraine dyes can be their tendency to form aggregates, which can lead to a substantial broadening of their absorption bands. Use of the present compounds in filters address these problems. The squarylium compounds of the present invention have the following formulas:

摘要: An investigation made by the inventors has found that when the pressure-sensitive adhesive layer having incorporated thereinto tetraazaporphyrin is used as a color correction member, the layer absorbs light having a wavelength around 545 nm, and hence the brightness of a panel including the layer reduces. A color correction member is disclosed that can satisfactorily achieve both of the widening of the color gamut of an image display apparatus and the prevention of a reduction in brightness thereof. A color correction member, which is characterized in that, when a value of an absorption peak at from 580 nm to 610 nm of an absorption spectrum is represented by Amax, and a value of an absorbance at 545 nm of the absorption spectrum is represented by A545, a ratio A545/Amax is 0.13 or less.

摘要: Provided is a polarizing film with a pressure-sensitive adhesive layer that can contribute to the widening of the color gamut of an image display apparatus, the polarizing film with a pressure-sensitive adhesive layer being suppressed in brightness reduction and being excellent in durability. The polarizing film with a pressure-sensitive adhesive layer of the present invention includes a polarizer and a pressure-sensitive adhesive layer arranged on at least one side of the polarizer. A distance between the polarizer and the pressure-sensitive adhesive layer is 25 μm or less. The pressure-sensitive adhesive layer has an absorption peak in a wavelength band in the range of from 580 nm to 610 nm. The pressure-sensitive adhesive layer contains a compound X represented by the general formula (I) or the general formula (II).
