Title:
METHOD FOR FORMING LUMINESCENT PATTERN OF ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
Japanese Patent JP2019079594
Kind Code:
A
Abstract:
To provide a method for forming a luminescent pattern of an organic EL element, which is superior in productivity and enables the luminescent pattern formation with high dimensional precision, and which enables the suppression of thermal deformation of a pattern-forming mask and the thermal damage to a plurality of organic EL elements and which enables the pattern formation on a plurality of organic EL elements at a time.SOLUTION: A method for forming a luminescent pattern of an organic electroluminescent element according to the present invention comprises the steps of: 1) putting an organic EL element sheet having a plurality of organic EL elements formed therein and shaped in a sheet form at a given location on a placement table with a cooling function for setting an object to be exposed to light; 2) disposing, by alignment by use of an alignment mark, a mask at a given location on the organic EL element sheet and bringing the mask into close contact therewith; 3) blowing a fluid against a surface of the mask; 4) applying light to the organic EL element sheet through the mask; and 5) then, stopping blowing the fluid against the mask surface.SELECTED DRAWING: Figure 1
