发明名称 THIN FILM ELECTROLUMINESCENT (EL) ELEMENT
摘要 <p>PURPOSE:To provide an EL element capable of displaying a large area and high accuracy by reducing resistance with a metal wire provided contiguously with a transparent electrode, thereby restraining scattering in current values flowing in picture elements. CONSTITUTION:On a glass substrate as an anode 2 an ITO(indium tin oxide) film is formed with the width of 1mm and thickness of about 200nm. Then, for reducing resistance of anode, as a metal electrode 3 an Al film is formed with the width of 0.5mm and thickness of about 200nm. The ITO film and Al film may well be jaxtaposed on a flat face or superposed vertically when they are brought into electric contact with each other. Thereon as a hole implantation layer a triphenylamine derivative is formed while as an illumination layer 8-hydroxy Al complex is formed, respectively with the thickness of 500Angstrom . Finally, as a cathode 6 an In film is formed with the width of 1mm and the thickness of about 200nm. A large diameter and high definition display with uniform brightness is made possible in this way.</p>
