Abstract
A marker for lens is provided as aligning unit in a lenticular lens that is of optical unit, and a marker for display panel is provided as aligning unit in a transmissive liquid crystal display panel that is of the display panel. Fixing unit is provided in at least a part of an area that encloses an image display area of the lenticular lens. An image display device is formed in such a manner that alignment between the lenticular lens and the liquid crystal display panel is performed by the marker for lens and the marker for display panel and the lenticular lens is fixed to a surface of the liquid crystal display panel on the side of a viewer.
Claims42
An image display device, comprising:
- a display panel which has a plurality of pixel sections each of which includes at least a pixel displaying an image for the first viewpoint and a pixel displaying an image for the second viewpoint, said pixel sections being provided periodically in one direction;
- and
- an optical unit refracts the light emitted from said pixels and emits the light in directions different from each other, and
- a fixing unit which is provide on at least a part of an area enclosing an image display area of said display panel, said fixing unit fixes said optical unit to said display panel.
A method of manufacturing a three-dimensional image display device includes,
- a display panel which has a plurality of pixel sections each of which includes at least a pixel displaying an image for the first viewpoint and a pixel displaying an image for the second viewpoint, said pixel sections being provided periodically in one direction, and
- an optical unit refracts the light emitted from said pixels and emits the light in directions different from each other,
- comprising the steps of:
- forming fixing means including a liquid adhesive in an area which encloses an image display area of said display panel or in at least. a part of the area corresponding to the area which encloses the image display area of said display panel in said optical unit;
- arranging said optical unit on said display panel;
- aligning said optical unit and said display panel by one or a plurality of aligning means which are formed in at least one of said optical unit and said display panel;
- and
- fixing said optical unit to said display panel by curing said adhesive.
A method of manufacturing a three-dimensional image display device includes,
- a display panel which has a plurality of pixel sections each of which includes at least a pixel displaying an image for the first viewpoint and a pixel displaying an image for the second viewpoint, said pixel sections being provided periodically in one direction, and
- an optical unit has a plurality of convex lenses that refracts the light emitted from said pixels and emits the light in directions different from each other,
- comprising the steps of:
- forming fixing means including an adhesive material in an area which encloses an image display area of said display panel or in at least a part of the area corresponding to the area which encloses the image display area of said display panel in said optical unit;
- and
- arranging said optical unit on said display panel to fix said optical unit to said display panel by curing said adhesive material, while said optical unit and said display panel are aligned with each other by one or a plurality of aligning means which are formed in at least one of said optical unit and said display panel.
