ABSTRACT:
An image display apparatus of head mounted type includes first and second liquid crystal display panels for displaying first and second images to be observed by right and left eyes, respectively of a user wearing the image display apparatus, an optical system for forming virtual images of the displayed first and second images such that the virtual images can be seen by the user, a controller for controlling electronically at least one of position, posture, size and shape of the first and second displayed images. The first and second images are smaller than display areas of the first and second liquid crystal display panels. In one embodiment, the controller includes a button for moving horizontally and vertically the displayed images on the display panels and a button for rotating the displayed images. In another embodiment, the controller includes a detector for detecting rotation and/or position of the apparatus and the displayed images are shifted and rotated and size or shape of the displayed images is changed such that the virtual images are seen to be stationary in a virtual image plane.
