| 1. An OLED display device for displaying a color image, the display device being viewed from a front side, comprising:
a) a plurality of OLED elements including a first OLED element that emits a first color of light and a second OLED element
that emits a second color of light different from the first color, each OLED element comprising a first electrode further
from the front side, a second electrode closer to the front side, and an organic electroluminescent element between the first
and second electrodes;
b) where the first electrode of each OLED element is reflective or a reflector is located behind the OLED elements;
c) a corresponding plurality of color filters aligned with the plurality of OLED elements, including a first color filter
for passing the first color of light emitted by the first OLED element and a second color filter for passing the second color
of light emitted by the second OLED element, and blocking other colors of light; and
d) a passivation film provided between the plurality of OLED elements and the corresponding plurality of color filters.
