摘要： A display device includes a light source, an optical waveguide, a light-extracting portion, a liquid crystal dispersion layer and a drive circuit. The optical waveguide has two ends to guide light from one of the two ends to the other end. The light is emitted by the light source. The light-extracting portion is provided to a side face of the optical waveguide. The liquid crystal dispersion layer is included in the light-extracting portion and includes liquid crystal droplets whose mean diameter is 100 nm or less. The drive circuit applies a voltage to the light-extracting portion to generate an electric field in the liquid crystal dispersion layer so that the light transmitting through the optical waveguide is scattered to be extracted.

摘要： A driving method of an image display apparatus includes the steps of: applying a non-selection potential to a first scanning wiring; and applying a selection potential to the first scanning wiring. A voltage applied to an electron-emitting device connected to the first scanning wiring is set to a voltage having a polarity reverse to that of a voltage to be applied upon emitting electrons during at least partial period of a period when the non-selection potential is applied to the first scanning wiring. The voltage applied to the electron-emitting device connected to the first scanning wiring is set to zero volt or to a voltage having a polarity same as that of the voltage to be applied upon emitting electrons and less than the threshold voltage, during a predetermined period before the selection potential is applied to the first scanning wiring.
