Abstract:
An optical waveguide sheet that has an auxiliary layer for preventing light transmitted through the waveguide sheet from leaking or being lost and a manufacturing method thereof. The waveguide sheet transmits light from a light emitting element thereinto, and has a reflecting pattern for reflecting light forward. At least one auxiliary layer for providing a total reflection condition for preventing the light from leaking or being lost when the light is transmitted into the waveguide sheet is coated on the waveguide sheet.
