Title:
LUMINESCENT DISPLAY
Document Type and Number:
Japanese Patent JP3711682
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a long-life luminescent display using an organic EL material by smoothening the form of the light emitting part of the luminescent display.
SOLUTION: In a luminescent display consisting of a luminescent material and an electrode material for nipping the luminescent material, it is formed of a plurality of round light emitting parts. In the formation of the round light emitting part, the form of the electrode is made by lithography, or a rectangular electrode is covered with an insulator, whereby the electrode is rounded. As the insulating material, a resist material is usable. In a matrix drive luminescent display, for example, an insulating film 29 is obtained by applying a resist material to the whole surface of a base 27 on which a TFT element 28 having a rectangularly formed ITO electrode 25 is put, circularly removing the resist material on the ITO electrode 25 by lithography. A precursor solution of organic EL material is charged onto the ITO electrode 25 the circumference of which is covered with the resist material, followed by baking, whereby an organic EL film is formed.
