1. A light emitting apparatus comprising:
a liquid crystal section having first and second surfaces and a liquid crystal layer between the first surface and the second surface that face each other;
a light emitting section that has a reflective polarizing film with a light output surface and outputs light from the light output surface with respect to the first surface in an oblique direction, the light output surface facing the first surface of the liquid crystal section; and
an optical component facing the second surface of the liquid crystal section, operable to receive light from the liquid crystal section, and having an interface portion and another interface portion, the interface portion being inclined with respect to the second surface, the another interface portion being parallel to the second surface, the interface portion and the another interface portion being bonded to the second surface by a first adhesive layer, and the interface portion and the another interface portion having refractive indices on a contact surface of the first adhesive layer that are different from a refractive index of the first adhesive layer,
wherein the optical component and the reflective polarizing film are on opposite sides of the liquid crystal section,
wherein the light emitting section includes a light source and a first optical sheet provided between the light source and the liquid crystal section in which the first optical sheet has a first prism surface disposed to face the light source,
wherein the light emitting section includes a collimation section that is provided between the light source and the first optical sheet that collimates light outputted from the light source, and
wherein the light emitting section further includes another optical sheet disposed between the light source and the first optical sheet and a second adhesive layer that fixes the another optical sheet to the first prism surface.
