Imaging devices have been proposed. As shown in FIG. 1, this 3D image device is a device in which a film 52 in which right-eye image display portions a and left-eye image display portions b are alternately arranged on the surface of a liquid crystal member 51 is attached. When a predetermined image is displayed by controlling the light emission of the member 51, a right-eye image is displayed from the right-eye image display unit a, and a left-eye image is displayed from the left-eye image display unit b. . And
The oscillation direction of the polarized light constituting the right-eye image from the right-eye image display unit a is configured to be polarized at an angle of 90 ° with respect to the oscillation direction of the polarized light constituting the left-eye image from the left-eye display unit b. (For example, the x component of the right-eye image composed of the two components x and y has a phase difference of 180 ° (π) with the x component of the left-eye image composed of the two components x and y. Therefore, when viewing the image with polarizing glasses including a right-eye lens with a polarizing plate that transmits only the right-eye image and a left-eye lens with a polarizing plate that transmits only the left-eye image, the observer sees a stereoscopic image. Can be thought of.

問題がある。A film 52 in which the right-eye image display portions a and the left-eye image display portions b are alternately arranged is a TAC film as disclosed in FIG. 2 of US Pat. No. 5,327,285. (Triacetylcellulose film) and an iodine-treated stretched PVA film (polyvinyl alcohol film) are laminated on a polarizing film, coated with a photoresist. After exposing a predetermined portion, the portion is treated with a potassium hydroxide solution to stretch the stretched PVA.
It is manufactured by a method that eliminates the property (phase difference function) that the film can rotate in the direction of linear polarization while vibrating light in a specific wavelength range of the film. However, since this method is a method of removing the photoresist by alkali treatment after treatment with a potassium hydroxide solution, the stretched PVA film is damaged by the alkali treatment, and the right eye image display part a and the left eye image display part are damaged. There is a problem that the function b is deteriorated.
