PROBLEM TO BE SOLVED: To provide an organic phosphorescent-light emitting device having a surface of an organic layer conditioned with an adjusting material for improving an efficiency in transport or injection of positive holes and electrons into a light emitting layer. SOLUTION: A adjusting layer is added onto one or both sides of the light emitting layer. The adjusting layer has an energy level substantially equal to that of the light emitting material. The light emitting diode has a first electrode, a light emitting layer connected to the first electrode and a second electrode connected to the light emitting layer. The light emitting layer contains a phosphorescent organic material. A first interfacial layer is arranged between the light emitting layer and the first electrode and has the thickness of about 3 nm or less, while containing an organic material that assists injection of a first charge into the light emitting layer.

PROBLEM TO BE SOLVED: To guarantee improvement of heat radiation from a chip, and in that case, to prevent remarkable change in the dimension of casing and increase in risk of delamination. SOLUTION: External terminals of a chip supporting member provided on a conductor frame and external terminals of a terminal section protrude from a cover, and all the terminals are molded so as to be simultaneously placed on a terminal board or a wiring board in a state where the terminals are mounted on the terminal board for mounting an element or the circuit board. At least three terminals are configured as thermal conductive terminals thermoconductively connected to the chip supporting member. The terminals protrude from the cover on various positions with intervals on at least two sides of the cover. Loss heat to be generated during operation of the element is radiated to the terminal board or the wiring board at three different points, and distributed with a large area.

PROBLEM TO BE SOLVED: To guarantee improvement of heat radiation from a chip, and in that case, to prevent remarkable change in the dimension of a casing and increase in risk of delamination. SOLUTION: An external terminal of a chip supporting member and external terminals of a first terminal portion and a second terminal portion protrude from a cover. The external terminals are initially bent toward the rear surface of a base on the outside of the base, and are bent toward the center of the base on the lower part of the base in a further extending portion, or are bent so as to separate from the base as the curved terminals. A thermal conduction terminal protrudes from the chip supporting member in two directions opposite to each other in two opposite sides of the cover in view of from the top of a conductive frame.
