Abstract
A plurality of display elements each includes two signal lines: S1 and S2. An electrode 4, which is one of the electrodes constituting an element capacitor Cp, is connected to the signal line S1 via a switching element TFT1, while the other electrode 5 is connected to the signal line S2 via a switching element S2. The gate electrodes of the switching elements TFT1 and TFT2 are connected to a single common scanning line G. With this structure the drive voltage applied to the element capacitor can be increased even when a TFT has a limited withstand pressure.
Claims4
A display device comprising:
- a display element having (i) a pair of substrates, at least one of which is transparent, (ii) a dielectric material layer provided between the substrates, and (iii) a display element including a first electrode and a second electrode for applying an electric field to the dielectric material layer so as to carry out a display, the first electrode and the second electrode being disposed on one of the substrates and connected to separate switching elements,
- the separate switching elements being turned off to apply no electric field to the dielectric material layer and being turned on to apply the electric field to the dielectric material layer,
- a medium sealed in the dielectric material layer, the medium exhibiting, when no electric field is applied thereto, optical isotropy in which a shape of a refractive index ellipsoid is globular and exhibiting, when the electric field is applied thereto, optical anisotropy in which the shape of the refractive index ellipsoid is non-globular.
