Provided is an optical module including a substrate, a light emitting element on the substrate, a light receiving element on the substrate, a first casing on the substrate and surrounds a periphery of the light emitting element, and a second casing on the substrate and surrounds a periphery of the light receiving element. Furthermore, the optical module includes a light emitting lens in the first casing on an optical axis of the light emitting element and a light receiving lens in the second casing on an optical axis of the light receiving element, in which a first diameter of one lens out of the light emitting lens and the light receiving lens in a first direction toward an optical axis of the other lens with reference to an optical axis of the one lens is shorter than a second diameter of the one lens in a second direction.

Optical module

Provided are an optical module and an image display apparatus, in which an adjustment position of a compensation plate is easily maintained even in a case where the image display apparatus is miniaturized, and a method of manufacturing the image display apparatus. An optical module including a fixing part that fixes an adjustment position of a phase difference compensation plate in a Z-axis direction perpendicular to a main surface of a liquid crystal panel; a projection type image display apparatus including a light source, a rotation body that rotationally adjusts, by an angle adjustment member, rotation of a phase difference compensation plate disposed between a liquid crystal panel and a polarized beam splitter of the liquid crystal panel, and a holder part that fixes the angle adjustment member of the rotation body to a fixing part in a Z-axis direction; and a method of manufacturing an optical module, the method including fixing an adjustment position of a phase difference compensation plate in a Z-axis direction perpendicular to a main surface of a liquid crystal panel.

Optical module, projection type image display apparatus, and method of manufacturing optical module

An optical element includes an effective diameter area that is centered on an optical axis and transmits an effective light beam, and a flange portion having, on a side surface around the effective diameter area, a slope that is not perpendicular to a direction of the optical axis.
