    摘要： [Objects]
    To provide polarizing film with superior optical properties and having a thickness of 10µm or less
    [Means for accomplishing the Objects]
    A polarizing film in the form of a continuous web is disclosed. The polarizing film comprises a polyvinyl alcohol (PVA) type resin having a dichroic material impregnated therein. The polarizing film is formed by stretching the PVA type resin, such that the thickness of the polarizing film is decreased to 10µm or less, and. The polarizing film has optical properties which satisfy conditions represented by formulae:
    P > -(10 0.929T-42.4 - 1) × 100 (where T
    P≥ 99.9 (where T ≥ 42.3)
    where T represents a single layer transmittance and P a polarization rate. The polarizing film can be made by providing a laminate comprising a PVA type resin layer formed on a non-crystallizable ester type thermoplastic resin substrate, and subjecting the laminate to a 2-stage stretching process comprised of a preliminary in-air stretching and an in-boric-acid-solution stretching.

The organic electroluminescent device comprises an organic electroluminescent element (2) and a polarized-light scattering film (1) which comprises a light-transmitting resin (11) and dispersedly contained therein minute regions (12) differing from the light-transmitting resin in birefringent characteristics and in which the difference in refractive index between the minute regions and the light-transmitting resin in the axis direction in which a linearly polarized light has a maximum transmittance, Δn 1 , is smaller than 0.03 and that in a direction perpendicular to the Δn 1 direction, Δn 2 , is from 0.03 to 0.5, the light produced by the organic electroluminescent element being emitted from the device through the polarized-light scattering film. Also disclosed are: a polarizing surface light source which comprises the organic electroluminescent device and which has an illuminating planar surface and emits a polarized light; and a liquid-crystal display which comprises the polarizing surface light source and a liquid-crystal cell disposed on the light emission side of the light source.
