PHOTOSENSITIVE RESIN COMPOSITION, WAVELENGTH CONVERSION SUBSTRATE AND LIGHT EMITTING DEVICE

摘要

A photosensitive resin composition includes a positive photosensitive resin having a photosensitive moiety that cleaves upon exposure to light, and a wavelength conversion material dispersed in the photosensitive resin. The photosensitive resin and the wavelength conversion material meet (i) to (iv):
(i) The photosensitive moiety and the cleavage product of the photosensitive resin do not neutralize the wavelength conversion material;(ii) The photosensitive moiety and the cleavage product do not induce hydrolysis of the wavelength conversion material;(iii) The HOMOs of the photosensitive moiety and the cleavage product are lower than the LUMO of the wavelength conversion material; and(iv) The LUMOs of the photosensitive moiety and the cleavage product are higher than the HOMO of the wavelength conversion material.(Any combination of a chemically amplified photosensitive resin with an acidic photosensitive moiety or cleavage product and an acidic wavelength conversion material is excluded.)

1. A photosensitive resin composition comprising:
a positive photosensitive resin having a photosensitive moiety that cleaves upon exposure to light; and a wavelength conversion material dispersed in the photosensitive resin, wherein the photosensitive resin and the wavelength conversion material meet the following (i) to (iv): (i) the photosensitive moiety and a cleavage product of the photosensitive resin do not neutralize the wavelength conversion material; (ii) the photosensitive moiety and the cleavage product do not induce hydrolysis of the wavelength conversion material; (iii) HOMOs of the photosensitive moiety and the cleavage product are lower than a LUMO of the wavelength conversion material; and (iv) LUMOs of the photosensitive moiety and the cleavage product are higher than a HOMO of the wavelength conversion material (excluding any combination of a chemically amplified photosensitive resin with an acidic photosensitive moiety or cleavage product and an acidic wavelength conversion material).
