Abstract: Increase in resolution of an organic EL display panel is made achievable with a relatively simple process. An emissive layer of an OLED is formed by stacking an R emissive layer, a G emissive layer, and a B emissive layer corresponding to an R color, a G color, and a B color. The glass-transition temperatures Tg-R, Tg-G, and Tg-B of the R emissive layer, the G emissive layer, and the B emissive layer are set to satisfy Tg-R<Tg-G<Tg-B. Due to laser irradiation, the G pixel is selectively annealed at an annealing temperature TA satisfying Tg-R<TA<Tg-G to make the R emissive layer of the G pixel lose an emission function. Further, the B pixel is selectively annealed at TA satisfying Tg-G<TA<Tg-B to make the R emissive layer and the G emissive layer of the B pixel lose the emission function.

Abstract: To provide a disk supporting apparatus, a disk holding apparatus and a disk apparatus whose planar dimension is minimized, and which can be manufactured simply and inexpensively. A plurality of supporting portions 44 inclines with respect to a top portion 46 as a vertex. A tray 26 is formed into a substantially triangular pyramid (three-dimensional) configuration, and a planar dimension of the tray 26 can be smaller than that of a conventional turntable. Accordingly, a plurality of disks can be mounted on the tray 26. The supporting portion 44 of the tray 26 can be placed in parallel to a door leaf without a slide mechanism that has conventionally been used for sliding a tray. Accordingly, a desired disk can be attached/detached merely by rotating and driving the tray 26, and a mechanism disposed at a stereo apparatus is made compact and manufactured inexpensively.

Abstract: A light emitting layer forming portion is provided on a semiconductor substrate, in which an active layer made of a compound semiconductor is sandwiched between a first and second clad layers made of compound semiconductor having band gap greater than that of the active layer, respectively and having a different conductivity type each other and furthermore a window layer is provided above the second clad layer. The second clad layer is made of a semiconductor having refractive index greater than that of the first clad layer. More preferably the window layer is made of a semiconductor having a refractive index greater than that of the second clad layer. As a result, the absorption of the light emitted from the light emitting layer in the semiconductor substrate can be reduced, and the light can be attracted toward the top surface so that the external quantum efficiency can be advanced.

Abstract: A semiconductor light emitting device is formed by adhering a semiconductor layered portion having a light emitting layer forming portion to a conductive substrate via a metal layer. The metal layer has at least a first metal layer for ohmic contact with the semiconductor layered portion, a second metal layer made of Ag, and a third metal layer made of a metal which allows adhesion to the conductive substrate at a low temperature. As a result, the rate of reflection of light from the metal layer increases due to the presence of Ag in the metal layer. Further, the metal in the metal layer is prohibited from diffusing into the semiconductor layer, so that the semiconductor layer does not absorb light. And therefore the brightness of the semiconductor light emitting device can further be increased.
