摘要： A liquid crystal display device includes a liquid crystal panel and an illumination unit. The illumination unit has a planar light emitting region formed by an EL element. The light emitting region is formed by a plurality of linear light emitting regions that extend in a direction perpendicular to the vertical scanning direction of liquid crystal. The linear light emitting regions are switched between a light emitting state and a non-light emitting state based on a command signal from a controller in a manner that the linear light emitting regions sequentially emit light in synchronization with vertical scanning of the liquid crystal. Each linear light emitting region is controlled to be in the non-light emitting state at least during a drive data rewriting period of a portion of the liquid crystal immediately above the linear light emitting region.

摘要： A luminescent panel has a light emitting portion for emitting isotropic light and a non-light emitting portion. A brightness compensating member has an incident portion and a light exit portion. The incident portion includes at least one inclined surface that is inclined relative to the light exit portion. The inclined surface is arranged to correspond to the non-light emitting portion. The inclined surface is configured so that the brightness of a section of the brightness compensating member that corresponds to the light emitting portion is substantially equal to the brightness of a section of the brightness compensating member that corresponds to the non-light emitting portion. Therefore, a substantially uniform brightness is obtained from the light exit portion.

摘要： An organic EL element that is an electroluminescence element has at least an organic layer held between a pair of electrodes. At least an electrode made of material having a higher volume resistivity, of the pair of electrodes, is formed in a flat form. The organic layer is provided with a plurality of non-light emitting portions. The non-light emitting portions are provided so that a larger number of non-light emitting portions exist per unit area at a position physically closer to the position of a terminal portion at which the electrode made of material having the higher volume resistivity is connected to an external connection terminal. As a result, the level of current passing per unit area is substantially uniform at each position on the element.

摘要： An area lighting unit has an electroluminescent device, a light scattering portion on a side of a light exit surface of the electroluminescent device, and a light covering portion on a side of a light exit surface of the light scattering portion. The light converging portion includes first and second layered optical sheets, each having a planar light incidence portion through which light enters and a light exit portion through which the light exits. The light exit portion of each optical sheet forms parallel prismatic protrusions, each having a vertex angle of 90 degrees to 105 degrees. The optical sheets each are so arranged that the light incidence portion is oriented to the electroluminescent device and a direction in which the protrusions of the first optical sheet are arranged is perpendicular to a direction in which the protrusions of the second optical sheet are arranged.

摘要： An electroluminescence element includes a first electrode, a second electrode, and a light emission layer arranged between the first electrode and the second electrode. The first electrode is formed of a material having a higher volume resistivity than that of the material of the second electrode. A connector portion electrically connects a feeder portion to the first electrode. The resistance value of the connector portion differs in correspondence with a position at which the connector portion connects the feeder portion to the first electrode. The brightness distribution of the electroluminescence element is thus adjusted to a desired state.
