1. A display unit comprising:
a display panel configured to display an image; an illumination device configured to illuminate the display panel; and a drive circuit configured to drive the display panel and the illumination device, wherein the illumination device includes a first transparent substrate and a second transparent substrate being separated from and facing each other, a light source emitting light to an end surface of the first transparent substrate or the second transparent substrate, a light modulation layer disposed in a gap between the first transparent substrate and the second transparent substrate, and exhibiting a scattering property or transparency with respect to light from the light source, depending on a potential difference, and a first electrode and a second electrode sandwiching the light modulation layer therebetween, the first electrode and the second electrode each include a plurality of strip-like electrodes, the strip-like electrodes of the first electrode and the strip-like electrodes of the second electrode extend in directions intersecting with each other, and the drive circuit drives the respective strip-like electrodes to allow an in-plane distribution of a potential difference between the strip-like electrodes of the first electrode and the strip-like electrodes of the second electrode to be constant within one frame period, when a two-dimensional image, a three-dimensional image, or an image including a two-dimensional image and a three-dimensional image is displayed on the display panel, wherein the drive circuit drives the respective strip-like electrodes to emit planar light in a first region corresponding to a two-dimensional image display region, and drives the respective strip-like electrodes to emit linear light in a second region corresponding to a three-dimensional image display region, wherein the plurality of strip-like electrodes of the second electrode include a plurality of first strip-like electrodes and a plurality of second strip-like electrodes, the first strip-like electrodes being used to generate the planar light, the second strip-like electrodes being used to generate the planar light and the linear light, and wherein the light modulation layer is in a normally black mode in which the light modulation layer is switched into a scattering state under voltage application and is switched into a transmission state under no voltage application, the drive circuit applies a fixed potential to strip-like electrodes passing through the second region selected from the plurality of strip-like electrodes of the first electrode and strip-like electrodes passing through the second region selected from the plurality of first strip-like electrodes, when an image including a two-dimensional image and a three-dimensional image is displayed on the display panel, and the drive circuit applies AC potentials with phases in synchronization with each other to strip-like electrodes not passing through the second region selected from the plurality of strip-like electrodes of the first electrode, strip-like electrodes not passing through the second region selected from the plurality of first strip-like electrodes, and all of the second strip-like electrodes, when the image including the two-dimensional image and the three-dimensional image is displayed on the display panel. |
