Title:
FORMATION METHOD OF OPTICAL SCATTERING LAYER, AND OPTICAL SCATTERING LAYER
Document Type and Number:
Japanese Patent JP2015200820
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a formation method of optical scattering layer capable of easily forming by an ink jet system a light diffusion layer excellent in light permeability and light diffusibility, and suitable for a thin film device, and an optical scattering layer.SOLUTION: A formation method of an optical scattering layer applies an ink on a transparent base material by an ink jet method, using the ink that contains fine particles with an average particle diameter of 100 nm or more and 500 nm or less and a refractive index of 1.7 or more, binder resin and contains an organic solvent having a boiling point of 250°C or less in 50 mass% or more and less than 95 mass%. The formation method includes a drying step of coating an image area F multiple times individually and drying the applied ink during the multiple application, under the conditions where, when a pixel length of each of pixels E configuring the image area F on which the optical scattering layer is formed is denoted by L, a dot diameter D of an ink droplet landed on the transparent base material satisfies 2×L≤D<4×L. The optical scattering layer formed by the method is also provided.
