Abstract

See full text

In a light guide device, a step between optical surfaces connected to each other by a connection portion can be limited to 1 mm or smaller so that a large stepped portion is not allowed to be formed at the connection portion in a hard coat formation process, whereby a coating liquid that flows along portions that are to form the optical surfaces forms no liquid pool or causes no liquid sagging. The light guide device can thus maintain satisfactory light guiding performance at the light guide portion.
