The invention relates to an alternative composite mask that is substantially composed of a transparent support film coated with a transparent polymer matrix that contains light-absorbing pigment particles or metal particles having an average particle size d50 ranging between 0.5 and 10 μm.
摘要:
The invention relates to a plastic film with an interference multilayer system applied thereon that comprises at least two layers. Said layers can be obtained by hardening and/or applying thermal treatment to a coating composition containing nanoscale inorganic solid particles having polymerizable and/or polycondensable organic surface groups, thereby forming a layer that is crosslinked by means of the polymerizable and/or polycondensable organic surface groups. The films can be used as an optical laminating film.

摘要:
A surface light source comprising a light emitting part (11) consisting of a single spot light source, and a light guide plate (12), wherein a reflection plane (13) is provided on the back side of the light guide plate and a prism pattern (15) is also provided. A directional light diffusion film (14) consisting of at least two light scattering/transmitting phases having different refractive indexes, where one phase having a larger refractive index includes a large number of regions having a columnar structure extending in the thickness direction of the film and the columnar structure is inclining against the normal direction of the film at an angle of 5-60°, is arranged on the light exit surface side of the light guide plate (12) such that the scattering direction of the directional light diffusion film becomes the direction of uneven luminance. Unevenness of luminance becomes inconspicuous especially when it is observed from an oblique direction and highly efficient brighter irradiation of light is ensured in the front direction of a screen.

A surface light source device comprises a light emitting section (11) made of a single spot light source, a light guide plate (12), a reflective surface (13) provided on the back side of the light guide plate, and a prism pattern (15). On the light emitting surface side of the light guide plate (12), there is provided a directional light scattering film (14) consisting of at least two phases having different refractive indexes and scattering light when transmitting it. One phase of a larger refractive index includes a plenty of areas having a columnar structure extending in the thickness direction of a film and arranged to be perpendicular to a normal to the film, and exhibiting a maximum scattering angle of 10-40°.
摘要:
An optical film composed by laminating a light scattering film 1 scattering and transmitting light and comprising at least two phases or more different in refractive index and a reflective polarizer 2 selectively P/S converting the light. It is preferred that at least one phase of the light scattering film larger in the refractive index has a columnar structure extending in the thickness direction of the film and the transmittance of the film in the normal direction is 4% or more. The optical film is excellent in visibility, is small in light loss in order to provide an excellently visible and bright image, and has an excellent light collecting property when used in a liquid crystal display device or the like.
摘要:
A process for producing a liquid-crystal cell by using a ferroelectric liquid crystal (FLC) composition containing at least one oleophilic substance that exhibits liquid crystallinity and at least one additive having lower boiling point than said substance, characterized in that said FLC composition is charged into the cell under high-temperature and high-vacuum conditions, provided that the two conditions will not overlap, or will overlap for a sufficiently short time to effectively prevent the evaporation of said additive.
