Method for manufacturing light guide device, light guide device, and virtual image display apparatus


During the manufacturing of the light guide device (20), the first and second bonding ribs (r1,r2) are used such that the light guide prism (10) and the opposing prism (50) are connected with each other from a specific offset direction. In this case, a difference between sizes of clearances between the first bonding surface (as) and the second bonding surface (bs) caused by a difference in inclination angles of the offset direction with respect to the first bonding surface is used such that a flow direction of the adhesive is controlled and filling is performed in a desire state, and thus high accuracy of the joint formed by the adhesive is maintained..
