Examples of the intermediate layer include a refractive index adjustment layer, an easily adhesive layer, a hard coat layer, and a crack prevention layer. These optical members can form an image display device such as a liquid crystal display (LCD) or an organic EL (electroluminescence) display (OLED).

  In recent years, optical members are used in various fields, and for example, image display devices are widely used as constituent members. Image display devices are widely used in various applications such as mobile phones, car navigation devices, monitors for personal computers, and televisions. As an optical member used when the image display device is an organic EL display device, in order to prevent external light from being reflected by a metal electrode (cathode) and viewed like a mirror surface, the viewing side surface of the organic EL panel A circularly polarizing film (a laminate of a polarizing film and a quarter wavelength plate, etc.) is disposed on the Moreover, a decorative panel etc. may be further laminated | stacked as an optical member in the circularly polarized film laminated | stacked on the visual recognition side surface of an organic electroluminescent panel.

  Although the adhesive sheet of patent document 1, 2 can control the transmittance | permeability of the light of wavelength 380nm, When the said adhesive sheet is used with an organic electroluminescence display, organic EL element by long-term use However, it was not enough. This is because the pressure-sensitive adhesive sheets described in Patent Documents 1 and 2 can absorb light with a wavelength of 380 nm, but the wavelength range (380 nm) on the shorter wavelength side than the light emitting region (longer wavelength side than 430 nm) of the organic EL element It is considered that the light of ̃430 nm is not sufficiently absorbed, and the transmitted light causes deterioration.

  Therefore, in order to suppress the deterioration of the organic EL element, the transmission of light with a wavelength (380 nm to 430 nm) on the short wavelength side of the light emitting region (longer than 430 nm) of the organic EL element is suppressed. It is necessary to use a layer having high transparency, which can ensure sufficient transmittance of visible light in the light emitting region of the above, for the organic EL display device. In addition, since the image display apparatus is used under a high temperature and high humidity environment, the image display apparatus is also required to have durability under severe environmental conditions.

  The present invention, when applied to an image display device, can form an optical member which can suppress deterioration of a display element, has high transparency, and is also excellent in durability under severe environmental conditions.

When the peak wavelength of ultraviolet light exceeds 500 nm, the photopolymerization initiator may not be decomposed and the polymerization reaction may not start. In addition, when the peak wavelength of ultraviolet light is less than 200 nm, polymer chains may be cut, and adhesion properties may be degraded.

(2-4) Anti-blocking layer 24
The antiblocking layer is a cured product layer of a resin composition containing a binder resin (base polymer) and particles, and has a flat portion and a raised portion on the surface, thereby providing high levels of handling properties and low reflection properties.

As a measurement sample, used is one in which particles are diluted to 1.0% by weight with ethyl acetate and uniformly dispersed using an ultrasonic cleaner.

  The height of the raised portion is set in consideration of the required slippage and the like.

The height of the raised portion is preferably 100 nm or more and 3 μm or less, more preferably 200 nm or more and 2 μm or less, and still more preferably 300 nm or more and 1.5 μm or less. By setting the height of the raised portion in the above range, it is possible to satisfy the blocking resistance of the transparent conductive film and at the same time, to sufficiently suppress light scattering and depolarization.

  The particles may be either polydispersed particles or monodispersed particles, but monodispersed particles are preferable in consideration of ease of application of the raised portions, light scattering prevention property, and the like. In the case of monodisperse particles, the particle size of the particles and the mode particle size can be regarded as substantially the same.

  The content of particles in the antiblocking layer is preferably 0.01 to 5 parts by weight, and more preferably 0.02 to 1 parts by weight with respect to 100 parts by weight of the solid content of the resin composition. More preferably, it is 0.05 to 0.5 parts by weight.

Moreover, the ultraviolet curing resin contains an ultraviolet polymerization initiator.

  In addition to the above-mentioned materials, additives such as a leveling agent, a thixotropy agent, an antistatic agent, a plasticizer, a surfactant, an antioxidant, a curing catalyst, and an ultraviolet light absorber can be used in the resin composition. The content of these additives, which is advantageous for the formation of projecting particles on the surface of fine asperity shape when a thixotropic agent is used, is usually about 15 parts by weight or less, preferably about 0 parts by weight with respect to 100 parts by weight of the ultraviolet curable resin. It is preferable to set it as 01 to 15 parts by weight. The resin composition forming the antiblocking layer can optionally contain a solvent.

  As the particles contained in the antiblocking layer 2, those having transparency such as various metal oxides, glasses, and plastics can be used without particular limitation. For example, cross-linked or not comprising various polymers such as inorganic particles such as silica, alumina, titania, zirconia and calcium oxide, polymethyl methacrylate, polystyrene, polyurethane, acrylic resin, acrylic-styrene copolymer, benzoguanamine, melamine and polycarbonate Examples thereof include crosslinked organic particles and silicone particles. The particles may be used alone or in combination of two or more, but organic particles are preferred. As the organic particles, acrylic resins are preferable from the viewpoint of the refractive index.
