摘要:
An object is to efficiently manufacture an organic EL display which uses microstructures. Microstructures are inlaid in a plurality of concavities in the surface of a nonconductive multi-holed substrate. On the multi-holed substrate, besides the concavities there is formed a plurality of through holes. The surface of the multi-holed substrate is covered with a nonconductive protective film. A transparent substrate on the surface of which is formed beforehand a transparent electrode layer is prepared, and the transparent substrate is attached to the rear face side of the multi-holed substrate. Contact holes are formed after which a luminous layer is formed inside the through holes by an ink jet method. The surface of the multi-holed substrate including the inside of the contact holes is covered with a metallic layer such as aluminum, and the metallic layer is then patterned, and negative electrodes and wiring are formed.

An ink jet printer head having a vibrating plate 5 with ink supply holes formed thereon, piezoelectric thin film 4, and electrodes (3 and 5) are formed on a substrate 60 with a separation layer interposed therebetween and the substrate is bonded to an ink jet base. The separation layer is irradiated with light to separate the substrate from the vibrating plate, piezoelectric thin film, and electrodes at the separation element; and the ink jet base is joined with the vibrating plate.

A display is provided which is constructed with a plurality of display blocks linked together so as to be continuous in the vertical direction. Each display block comprises a display portion having a flat rectangular shape with a plurality of pixels which emit light using organic EL elements, arranged over the entire face in a matrix, and a terminal portion provided continuous with one of the short sides of the display portion for relaying signals or power from the outside to each pixel. Each display block is attached on a transparent substrate via a transparent adhesive so that the long sides of the display portion are contacted and are vertically continuous. The display surface of the display portion (the surface on the side which the emitted light in the organic EL element illuminates) faces towards the transparent substrate side. As a result, the light from the display portion shines from the surface of the transparent substrate to the outside.

An object is to efficiently manufacture an organic EL display. A circuit substrate 10 in which is set microstructures 12 and which is formed with wiring 14, and a transparent substrate 20 formed with a transparent electrode 21, an emissive layer 25 and a cathode layer 26, are stuck together with the side formed with the wiring 14 and the side formed with the cathode layer 26 facing the inside, to thereby manufacture an organic EL display 30. In the sticking together of the circuit substrate 10 and the transparent substrate 20, an anisotropic conductive paste or an anisotropic conductive film can be used.
摘要:
An EL driving circuit which can operate at a satisfactory operation speed is disclosed. A voltage higher than the voltage for operating the EL element is input, and the input voltage is stepped down by the voltage step-down circuit (2) which is provided in each unit block (1). The stepped-down voltage is then supplied to a transistor (3) functioning as the driving element for driving the EL element. Therefore, even when the number of EL elements increases, sufficient source voltage can be supplied to each unit block.
