Abstract
A display device is provided which is able to effect high visibility display utilizing external light, and which is able to effect reflective display with a combination of various textures and color. The display device includes a first polarized-light separating member for transmitting a linearly polarized light component polarized in a first direction, a transmitted light polarization axis changing device capable of selecting states of changing and not changing a transmitted light polarization axis, a second polarized-light separating member for transmitting a linearly polarized light component in a polarized second direction and for mirror-reflecting a linearly polarized light perpendicular to the linearly polarized light component, and a reflecting element disposed in that order. Coloring layers or light-diffusing layers are formed on the surface or the back of the second polarized-light separating member.
