An optical modulation device comprises a first substrate having thereon a first conductor film, a second substrate having thereon a second conductor film disposed opposite to the first conductor film, and an optical modulation material disposed between the first and second substrates. The optical modulation device is driven by forming a potential gradient along the extension of the first conductor film or both the first and second conductor films, and applying an information signal to the first or second conductor film.

There is provided an organic light-emitting apparatus in which the luminance can be improved, and, at the same time, the reflection of ambient light can be reduced by adding a prism member and a light-absorbing member to a spontaneous light-emitting device such as an organic light-emitting device, and which includes: a plurality of organic light-emitting devices each having a pair of electrodes and an organic compound layer formed between the pair of electrodes; a prism member disposed on a light extraction side of the organic light-emitting device, an interface on the light extraction side of the prism member being an interface with air; and a light-absorbing member formed between the plurality of organic light-emitting devices, around the prism member, and on a side portion of a protrusion of the prism member.
摘要:
An object of the present invention is to maintain sufficient light extraction from an organic light emitting device and reduce reflection of external light. There are arranged a polarizing member, a prism member, a phase member, and an organic light emitting element which has an organic light emitting layer arranged between a pair of electrodes, in mentioned order from the side of a light extraction surface. When the prism member includes two sheets, the vertex angle of the prism member sheet arranged on the side of the organic light emitting element is preferably a vertex or less of the prism member arranged on the side of the light extraction surface. Furthermore, the prism members are preferably arranged so that pitch directions thereof are orthogonal to each other.

An organic EL light-emitting apparatus includes a base, an organic EL device, a prism member, a polarizing member, and a phase member. The prism member, the polarizing member, and the phase member are adjacent to a light extraction side of the organic EL device. The prism member includes a plurality of unit prisms each having a triangular-column shape. The unit prisms are arranged such that their longitudinal directions are parallel to one another. The polarizing member is disposed further from the base than the prism member. The prism member has an apex angle between 90° to 140°.
