Abstract:
A lightguide includes: a coupling structure ( 32 ) having a light-receiving surface to receive a light beam from a display element ( 10 ); and a light guide plate ( 32 ) which includes a first light-guiding layer ( 33 A) having a prism surface ( 35 ) that is disposed so as to partially transmit the light beam entering from the coupling structure and propagating therein, and which includes a second light-guiding layer ( 33 B) covering the prism surface, the light guide plate having an outgoing surface (S 1 ) via which the light beam having been transmitted through the prism surface is allowed to exit. A refractive index of the coupling structure ( 32 ) is different from a refractive index of the light guide plate ( 32 ).

Claim (Index 13):
The lightguide of  claim 1 , wherein the second light-guiding layer is a planarization layer for planarizing the prism surface, the planarization layer having a substantially flat surface.
