摘要： After entering a transparent substrate 9 of an organic EL device and passing through this substrate 9, an outside light L1 further passes through a transparent layer 10, a transparent electrode 12, and an organic light emitting layer 13 to be reflected by a reflective electrode 14. Herein, the reflective electrode 14 has irregularities and therefore the outside light L1 is diffused and reflected by this at various angles. These reflected lights are further diffused when passing through a boundary between the organic light emitting layer 13 and the transparent electrode 12 and through an irregularity surface 11 of the transparent layer 10, and outgo from the transparent substrate 9 toward a liquid crystal panel. On the other hand, lights L2 to L4 emitted from the organic light emitting layer 13 are diffused when passing through the boundary between the organic light emitting layer 13 and the transparent electrode 12 and through the irregularity surface 11 of the transparent layer 10, and outgo from the transparent substrate 9 toward the liquid crystal panel.

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： 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： 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.
