Abstract
A display section of a portable phone includes a first polarizer, a switching panel section, a reflective polarizer, and a main panel section. The switching panel section has a liquid crystal layer including a plurality of regions having at least two different alignment directions. This makes it possible, by utilizing the difference in the alignment direction of the liquid crystal layer, to make the image difficult to observe by a sight-line from an oblique direction. Furthermore, it is also possible, by utilizing the mirror-surface displaying caused by the reflective polarizer, to make the image significantly difficult to observe.
