Summary:PROBLEM TO BE SOLVED: To achieve an organic EL display device of bottom emission structure including a color filter easily.SOLUTION: An organic EL display device includes a display device body 1 and a color filter 30 separately from each other. The display device body 1 includes a base substrate 2 having a first surface 2a and a second surface 2b facing oppositely from each other, and a plurality of pixels 3 arranged on the first surface 2a of the base substrate 2. Each of the plurality of pixels 3 includes a plurality of sub-pixels 4R, 4G, 4B. When viewing from a direction perpendicular to the first surface 2a and second surface 2b, the outer edge of each of the plurality of sub-pixels includes a plurality of sides. The thickness of the base substrate 2 is within a range of 1/50-1/2 of the length of shortest side out of the all sides included in the plurality of outer edges of the plurality of sub-pixels. The color filter 30 is stuck to the second surface 2b of the base substrate 2. 【課題】カラーフィルタを備えたボトムエミッション構造の有機EL表示装置を容易に実現する。【解決手段】有機EL表示装置は、互いに別個の表示装置本体1とカラーフィルタ30とを備えている。表示装置本体1は、互いに反対側に向いた第1の面2aおよび第2の面2bを有するベース基板2と、ベース基板2の第1の面2aの上に配列された複数の画素3とを備えている。複数の画素3の各々は、複数の副画素4R,4G,4Bを含んでいる。第1の面2aおよび第2の面2bに垂直な方向から見たときに、複数の副画素の各々の外縁は複数の辺を含んでいる。ベース基板2の厚みは、複数の副画素の複数の外縁に含まれる全ての辺のうち最も短い辺の長さの1/50から1/2の範囲内である。カラーフィルタ30は、ベース基板2の第2の面2bに貼り付けられている。【選択図】図1
