Abstract: A light guiding plate guides light from a light source and irradiates the light onto a display portion. The light guiding plate has an exit plane facing the display portion, and a reflection-exit plane opposite to the exit plane. The reflection-exit plane has a first end intersecting the incidence plane and a second end intersecting the opposite end plane. An inclination angle defined by the incidence plane and a line that contains the first end and the second end is greater than 0.2° and less than 0.75°. The reflection exit plane includes a light admission portion that reflects light entering through or reflected on the incidence plane to the exit plane. This minimizes the parallax to an invisible level to improve the visibility while improving the uniformity of the brightness distribution.

Abstract: A light guiding plate guides light from a light source and irradiates the light onto a display portion. The light guiding plate has an incidence plane, which permits light to enter the light guiding plate, an opposite and plane opposite to the incidence plane an exit plane facing the display portion, and a reflection-exit plane opposite to the exit plane. A plurality of grooves are formed on the reflection exit plane. In any adjacent pair of the grooves, the depth of the groove closer to the opposite end plane is equal to or greater than the depth of the groove closer to the incidence plane. The depth of the grooves substantially increase from the incidence plane toward the opposite end plane. This improves the uniformity of brightness distribution.

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: 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.

Abstract: Respective glass substrates 1 of a pair of such EL devices 3 are disposed in such a manner that EL element portions 2 formed on their respective front surfaces 1a are opposed to each other. Spacers 4 are disposed between the two glass substrates 1 so that the EL element portions 2 are separated from each other and do not interfere with each other. In this state, peripheral portions of the two glass substrates 1 are bonded to each other with a sealing material 5, whereby a hollow portion 6 formed between the two glass substrates 1 is sealed with the sealing material 5 and isolated from the outside. Then, the two glass substrates 1 that are integrated together are immersed in an etching liquid, that is, they are subjected to thinning processing.
