Abstract: 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.

Abstract: 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.

Abstract: A light guiding plate guides light from a light source to illuminate a liquid crystal cell. A reflector reflects light from the light source. A first surface and a second surface selectively transmits or reflects light. A first region is formed on the first surface at a location that is relatively near the light source. The first region includes a first inclined face and a second inclined face. The first inclined face reflects light from the light source to guide light to the reflector. The second inclined face reflects light from the light source to the second surface so that the second surface emits light. A second region is formed on the first surface at a location that is relatively far from the light source. The second region includes a third inclined face and a fourth inclined face. The third inclined face reflects light from the light source to the second surface so that the second surface emits light. The fourth inclined face reflects light reflected by the reflector to the second surface so that the second surface emits light.

Abstract: 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.
