Abstract: PROBLEM TO BE SOLVED: To improve the hole filling performance and electron filling performance, save the power consumption, and prolong the lifetime by having a hole filling layer between a positive electrode and a hole transport layer, and having an electron injection layer between a negative electrode and an electron transport layer. SOLUTION: In an EL element, direct current voltage is applied between a positive electrode 2 and a positive electrode 4 so that hole, which is filled from the positive electrode 2 through a hole filling layer 11, arrives a light emitting layer 7 through a hole transport layer 6 and so that electron, which is injected from the negative electrode 4 through an electron injecting layer 12, arrives the light emitting layer 7 through an electron transport layer 8. As a result, in the light emitting layer 7, recombination of the electron/hole is generated so as to generate the singlet exciton, and the light emission having the predetermined wavelength is generated. In the case of a layer structure (b), in which the light emitting layer is omitted, the light emission having the predetermined wavelength is generated from an interface of the hole transport layer 6 and the electron transport layer 8. These light emission is observed from a substrate 1 side. In the case of a transmission type EL element expressed with a figure (a), light emission can be observed from a protecting layer 5, besides from the substrate 1 side.

Abstract: PROBLEM TO BE SOLVED: To prevent deterioration caused by radiation heat when an insulative sealing film is to be formed continuously by forming an optical element consisting of a laminate of a light emission region and electrode under the vacuum film forming conditions, and forming a conductive sealing film while vacuum state is retained. SOLUTION: By means of mask evaporation, an ITO transparent electrode 5 of 100nm thick, a TPD hole conveying layer 4 of 500nm thick, Alq3 light emission layer 3 of 50nm thick, and LiAl alloy metal electrode 1 of 2kÅ thick are laminated in the sequence as named on a glass board 6 in a patten of picture element dots so that an organic EL element is formed. The evaporation mask is replaced within the same vacuum chamber, and a conductive sealing film 7 of gold of 10kÅ thick is put as enclosing the surfaces of the picture element dots consisting of laminate of the transparent electrode 5, hole conveying layer 4, light emission layer 3, and metal electrode 1. Further the evaporation mask is replaced in the same vacuum chamber, and an insulative sealing film 8 of SiO2 of 2kÅ thick is put as enclosing the conductive sealing film 7. Likely deterioration of the organic layer at this time caused by the radiation heat is reduced by existence of this film 7.

Abstract: PURPOSE:To reduce error rate at the time of recording and reproduction due to the peeling or falling of the edge part of a recording layer. CONSTITUTION:When a recording layer 3 capable of optical recording and/or reproduction of information and a protective layer 4 are formed on the top of a substrate 2 to obtain an optical recording medium, the recording layer 3 is formed on the top of the substrate 2 except the edge part 84 of the substrate 2. Since the edge part 84 of the substrate 2, that is, the part 90 not coated with a soln. for the recording layer is subjected to slitting, the edge part 84 of the recording layer 3 is prevented from cracking.

Abstract: PROBLEM TO BE SOLVED: To provide an organic electric-field light-emitting element that inhibits the occurrence of unevenness in film thickness in a wet organic layer and a manufacturing method for the same, and a display.
SOLUTION: Each organic EL element 10R, 10G, and 10B is formed by laminating a first electrode 11 arranged for each pixel, an insulating film 12, an inorganic oxide film 13, a hole injection layer 14, a hole transportation layer 15, a light-emitting layer for each color, an electron transportation layer 17, an electron injection layer 18, and a second electrode 19, in this order on a drive panel 10. The insulating film 12 is provided with an opening 12a exposing the first electrode 11. The inorganic oxide film 13 is continuously formed over an area from the central area D1 to the peripheral edge area D2 of the opening 12a. The hole injection layer 14 includes a wet hole-injection material and is film-formed on the inorganic oxide film 13 by a wet method. Consequently, it is possible to inhibit the occurrence of film defects or the like in the hole injection layer 14 due to the difference in wettability with respect to each surface of the insulating film 12 and the first electrode 11.
