Document Type and Number:
WIPO Patent Application WO/2008/018137
Kind Code:
A1
Abstract:
Provided is an optical device having a self light emitting element wherein an
organic light emitting functional layer including a light emitting layer is
sandwiched between a pair of electrodes. Light emission failures due to entry
of deteriorating factors are reduced in a region where an upper electrode overlaps
the organic light emitting functional layer. In a self light emitting element
(organic EL element)(100) as one pixel (11), an organic light emitting functional
layer (5) including a light emitting layer (52) is sandwiched between a lower
electrode (3) and an upper electrode (6). In an optical device (1), one or a plurality
of pixels(11) are formed directly or through other layers on a substrate (2).
The optical device is provided with an organic material layer (7) formed on the
upper electrode (6); an inorganic layer (8) formed on the organic material layer
(7), in a status where insulation between the lower electrode (3) and the upper
electrode (6) is ensured; and a sealing section (9) for sealing the self light
emitting element formed on the substrate with a sealing material. An end portion
of a region (interface (78)), in which the organic material layer (7) overlaps
the inorganic layer (8), is separately formed by having the organic material
layer (7) in between, on an outer end side of the sealing section (9) outside the
end portion of a region (interface (56)) wherein the organic light emitting functional
layer (5) overlaps the upper electrode (6).
