Claim:
1. A display device that displays at least first and second images by emitting light in at least two directions, respectively, from each of a plurality of pixels, comprising: a light source; a first substrate over the light source, said first substrate restricting light from the light source; and a second substrate over the first substrate, said second substrate restricting light that originated from the light source and that has passed through the first substrate, wherein each of the pixels has an electrically conductive light-shielding member movably disposed between the first and second substrates, and driving electrodes that cause the light-shielding member to move to prescribed positions, wherein the display device further comprises a driving control unit that drives said driving electrodes to move the light-shielding member to the respective prescribed positions for each of the pixels, wherein, at each of the pixels, the first substrate has one or more of first apertures that transmit light, wherein, at each of the pixels, the second substrate has one or more of second apertures that transmit light, wherein, at each of the pixels, said one or more of the first apertures and said one or more of the second apertures are configured to define at least a first optical path and a second optical path that are different from each other for the light from the light source, wherein, in order to display the first image, at each of the pixels, the driving control unit causes the light-shielding member to move between a first position where the first optical path is not blocked and the second optical path is blocked by the light-shielding member and a second position where the first and second optical paths are both blocked by the light-shielding member, and wherein, in order to display the second image, at each of the pixels, the driving control unit causes the light-shielding member to move between a third position where the first optical path is blocked and the second optical path is not blocked by the light-shielding member and a fourth position where the first and second optical paths are both blocked by the light-shielding member.
