[0078] The first example relates to the display device according to the first embodiment of the present invention. More specifically, the first embodiment relates to the binocular type display device of the present invention, the display device of the first configuration of the present invention, and the display device of the third configuration of the present invention. image 3 A perspective view illustrating a main part of the display device when the observer wears the display device. Figure 4 A view of a plane mirror and the like included in the optical system of the right-eye image display device viewed along the x-axis direction is illustrated. Figure 5 A conceptual view (perspective view) of the image forming apparatus and the optical system when viewed from the observer side is illustrated. Figure 6 A conceptual view (perspective view) of the image forming apparatus and the optical system when viewed from above is illustrated. and, Figure 7A Illustrated is a per...

[0127] The second embodiment is a modified example of the first embodiment. Figure 13A A schematic cross-sectional view of a supporting member and an image forming device included in the image display device of the second embodiment is illustrated. Figure 13B A schematic cross-sectional view of a support member is illustrated. Figure 13C A schematic plan view illustrating a support member and an image forming apparatus. Figure 13D Illustrating the supporting member and the image forming device along Figure 13A Schematic cross-sectional view of arrow D-D in .

[0128] In the image display device of the second embodiment, the peripheral portion of the image forming device 40 extending in the X direction is supported by the support member 60 2 Clamping. support member 60 2 A lower member 66A and an upper member 66B are included. With the combination of the lower member 66A and the upper member 66B, a kind of frame member is constituted. In support member 60 2 A groov...

[0131] The third embodiment is a modified example of the second embodiment. In the third embodiment, the image forming device 40 is also curved. However, unlike the second embodiment, the degree of curvature can be varied. Figure 14A A schematic cross-sectional view of a support member and an image forming device included in an image display device of a third embodiment is illustrated. Figure 14B A schematic plan view illustrating a support member and an image forming apparatus.

[0132] In the third embodiment, there is a gap between the groove portion 66C and the peripheral portion of the image forming device 40 extending in the X direction. Then, on the support member 60 3 A protruding portion 67A and a threaded portion 67B are provided on the side surface extending in the X direction. support member 60 3 It is housed in a casing (not shown), and the upper part of the casing is opened. The case is attached to an upper portion of each of the frame bodies 53R and 53L....

Abstract

This display device has a frame, an image display device attached to said frame, and a distortion correction device. The image display device has an image formation device and an optical system that directs an image from said image formation device to a viewer's pupil. The image formation device is curved in an X direction, said X direction being an image-formation-device direction corresponding to a first image direction, and a Y direction, said Y direction being an image-formation-device direction corresponding to a second image direction that is different from the first image direction. The distortion correction device corrects an inputted image signal so as to correct distortion in viewed images.

Description

technical field [0001] The present invention relates to display devices. More specifically, the present invention relates to a display device that can be used as, for example, a head mounted display (HMD: head mounted display). Background technique [0002] For example, a virtual image display device (display device) is known from Japanese Patent Application Laid-Open No. 5-134208 for allowing an observer to observe a two-dimensional image formed by an image forming device as an enlarged virtual image using a virtual image optical system . [0003] In the virtual image display device disclosed in Japanese Patent Application Publication No. 5-134208, the light from the light source and collimated by the lens through the polarizer illuminates the liquid crystal display part, and the image light of the illuminated liquid crystal display part is captured by the The lens group is focused at the first focal point. The collected light is then reflected by a concave mirror, passe...
