Abstract
In a three-dimensional image display device using a liquid crystal parallax barrier panel, a liquid crystal display panel is first roughly aligned with the liquid crystal parallax barrier panel using an alignment mark. Subsequently, a white pattern for two pixels is formed in the center of a screen. When an observer's eyes are brought close to the screen, a blue pattern is generated in the center, and a white pattern is generated on both sides of the blue pattern. The relationship between a width dof the blue pattern and a width dof the white pattern is d=2d, and the tilt of the blue pattern is set in a predetermined range, so that necessary alignment accuracy can be secured.
