Abstract: This image display unit includes an image display panel and a barrier liquid crystal panel. The barrier liquid crystal panel appropriately controls a potential applied to one or the plurality of electrodes forming the scan-side transparent electrode (105) and the common-side transparent electrode (104) according to an operation mode that is specified, changes a slit width and a slit pitch of the slits (100S, and switches a function to one of the three functions of the 2D display function that emits image light for 2D display from the pixels, the 3D display function that emits image light for 3D display from each of pixels for left eye and pixels for right eye of the pixels, and the viewing angle control function that controls a viewing angle of the image light from the pixels.

Abstract: Under an LCD panel (241) a prism sheet (242) is provided, and a light beam is emitted in a first direction (243) at a timing that a first LED group (247) is turned on, so that an eye (202L) located at this position can view a first image (211). When a second LED group (248) is turned on the light beam is emitted in a second direction (244), so that the eye (202R) located at this position can view a second image (212). These images (211, 212) are combined to thereby constitute a larger image.

Abstract: Portable terminal (20) of this invention includes image display portion (7) that displays an image, and key operation portion (8) that displays an image corresponding to a function and/or input keys (4a) corresponding to a function and that enables an input operation using input keys (4a). Key operation portion (8) includes transmission/diffusion switchable film (2) that transmits or diffuses light from light source (3).
