IMAGE DISPLAY DEVICE AND IMAGE GENERATING DEVICE
First Claim
1. An image display device, comprising:
- a plurality of light emitting units, arranged in an array comprising a plurality of rows extending in a first direction, each of the plurality of light emitting units having an optical axis; and
a plurality of microlenses, arranged in an array so that light emitted from each of the plurality of light emitting units passes through a corresponding one of the plurality of microlenses, each of the plurality of microlenses having an optical axis;
wherein the optical axis of light emitting units in at least one of the plurality of rows is offset from the optical axis of the corresponding microlenses in the at least one of the plurality of rows.

Abstract
There is provided an image display device including an image generating device, and a light guide unit. When a point at which light output from a center of the image generating device is incident is a point O, a normal line passing through the point O in a portion of the unit is an X axis, an axis of the unit passing through the point O is a Y axis, an optical axis of light incident at the point O among light beams output from a center of the image generating device is a ζ axis, and a virtual plane including the ζ axis and the Y axis is a ζY plane, light output from the image generating device and incident at a point (0,Y1,Z1) forms an angle θZ with the ζY plane and forms an angle θY with an XZ plane, and when Z1≠0, θZ≠0Y is satisfied.

20. An image display device, comprising:
-
a plurality of light emitting units, arranged in an array comprising a plurality of rows, the plurality of rows comprising at least one first row; and a plurality of microlenses, arranged in an array so that light emitted from each of the plurality of light emitting units passes through a corresponding one of the plurality of microlenses, each of the plurality of microlenses having an optical axis; wherein light from a light emitting unit in a particular row passes through a corresponding microlens at an angle to the optical axis, and the angle varies as a function of a distance between the particular row and the at least one first row.
