Claim Text:
1. A display device of transflective type comprising: a display panel; and a backlight, said display device carrying out, in a switchable manner, (i) reflection display by reflecting light entered from outside and (ii) transmission display by causing light from the backlight to pass through, the display panel including: a first substrate which has a first electrode, a second substrate which has a second electrode and is arranged so as to face the first substrate, and an optical modulation layer which contains a plurality of shape-anisotropic members and is provided between the first substrate and the second substrate, each of the plurality of shape-anisotropic members (i) having a reflection surface and (ii) changing, by rotation, an area of a projection image viewed in a normal direction of the substrate, said display device controlling a transmittance of light, which has entered the optical modulation layer, by rotating the plurality of shape-anisotropic members by changing a frequency of a voltage applied between the first electrode and the second electrode, and said display device displaying black by multiple reflection of the light that has entered the optical modulation layer and is reflected by the plurality of shape-anisotropic members which are oriented so as to abut on one of the first substrate and the second substrate such that a major axis of each of the plurality of shape-anisotropic members extends in parallel with the one of the first substrate and the second substrate.
