The recent invention provide an organic electroluminescence display device
with color purity adjustment, particularly white purity increased,
without increasing formation processes. For each of unit pixels formed on
an insulating film INS formed on a principal surface of a glass
substrate, a bank BNK is provided on a bottom electrode BEL being a pixel
electrode. The bank BNK has the shape of a bank that surrounds a pixel
concerned, for each of pixels, and an organic electroluminescence light
emitting layer is charged within a region surrounded by the banks BNKs.
Between the banks BNKs, a green light emitting layer (G light emitting
layer), a blue light emitting layer (B light emitting layer), and a red
light emitting layer (R light emitting layer) are provided. At the same
time as the formation of these color light emitting layers, light
emitting layers of three colors, the green light emitting layer (G light
emitting layer), the blue light emitting layer (B light emitting layer),
and the red light emitting layer (R light emitting layer) are stacked on
a region of a white pixel to form a white light emitting layer (G+B+R).
An upper electrode UEL is formed over the green light emitting layer (G
light emitting layer), the blue light emitting layer (B light emitting
layer), the red light emitting layer (R light emitting layer), and the
white light emitting layer (G+B+R light emitting layer).
