Abstract
An electroluminescent display in which a dielectric breakdown of a luminescent element is suppressed has luminescent elements disposed between first and second substrates, where the first and second substrates are deformed into a convex shape to improve breakdown characteristics.
Claims11
A method of manufacturing an electroluminescent display, said method comprising the steps of:
- forming an inlet in one of a first substrate and a second substrate;
- laminating a luminescent element on said first substrate;
- disposing said second substrate at a predetermined distance away from said first substrate in an environment having a predetermined pressure;
- sealing a region of said first substrate away from said luminescent element to a corresponding portion of said second substrate, thereby forming an internal space between said first and second substrates;
- and
- injecting insulating fluid into said internal space from said inlet by utilizing a pressure higher than said predetermined pressure, thereby deforming said first and second substrates into a convex shape.
A method of manufacturing am electroluminescent display, said method comprising the steps of:
- forming an inlet in one of a first substrate and a second substrate;
- laminating a luminescent element on said first substrate;
- disposing said second substrate at a predetermined distance away from said first substrate;
- disposing spacers between said luminescent element and said second substrate;
- sealing a region of said first substrate away from said luminescent element to a corresponding portion of said second substrate using a sealing section, thereby forming an internal space between said first and second substrates, said spacers deforming said first and second substrates to have a convex shape;
- relatively pressurizing said first substrate and said second substrate;
- and
- injecting insulating fluid into said internal space from said inlet.
A method of manufacturing an electroluminescent display, said method comprising the steps of:
- forming an inlet in one of a first substrate and a second substrate;
- laminating a luminescent element on said first substrate;
- disposing said second substrate at a predetermined distance away from said first substrate;
- sealing a region of said first substrate away from said luminescent element to a corresponding portion of said second substrate, thereby forming an internal space between said first and second substrates;
- placing said sealed substrates in an environment having a reduced pressure lower than an external pressure;
- and
- injecting an insulating fluid into said internal space from said inlet by utilizing a pressure higher than the reduced pressure while maintaining the environment at the reduced pressure, thereby deforming said first substrate and said second substrate into a convex shape.

- laminating a luminescent element on said first substrate;
- disposing said second substrate at a predetermined distance away from said first substrate in an environment having a predetermined pressure;
- sealing a region of said first substrate away from said luminescent element to a corresponding portion of said second substrate, thereby forming an internal space between said first and second substrates;
- and
- injecting insulating fluid into said internal space from said inlet, thereby deforming said first substrate and said second substrate into a convex shape;
- wherein said inlet forming step is performed before said laminating step.
