Title: LIGHT SCATTERING FILM, LIGHT EMITTING ELEMENT, LIGHT SCATTERING FILM MANUFACTURING METHOD, AND LIGHT EMITTING ELEMENT MANUFACTURING METHOD
Abstract:
A light scattering film (200) is provided with a light transmitting film (120), and a plurality of light scattering walls (123) that are disposed in the light transmitting film (120). The light scattering walls (123) are disposed to intersect a surface (120a) of the light transmitting film (120), said surface being on the light extracting side. The light scattering walls (123) are repeatedly disposed in the direction parallel to the surface (120a) on the light extracting side. A light emitting element (100) has a light extraction surface (1) through which light is extracted. The light emitting element (100) is provided with: a light transmitting substrate (110); the light transmitting film (120) that is disposed to overlap the light transmitting substrate (110); and the light scattering walls (123) that are disposed in the light transmitting film (120). The light scattering walls (123) are disposed to intersect the light extraction surface (1). The light scattering walls (123) are repeatedly disposed in the direction parallel to the light extraction surface (1).
