有機ELディスプレイ
Document Type and Number:
Japanese Patent JP5378392
Kind Code:
B2
Abstract:
Provided is a color conversion organic EL display which improves the efficiency of the entire display by increasing the proportion of light beams incident on a color conversion filter among light beams emitted from a light-emitting portion. A color filter (20) and a black matrix (30) are formed on a glass substrate (10), and a color conversion filter (40) is formed on the color filter and the black matrix. A transparent electrode is formed on another glass substrate (70), and an organic EL light-emitting portion (60) is formed on the transparent electrode. The two substrates are bonded via a filler (50). The opening area ratio and positional relationship between the organic EL light-emitting portion (60) and the color conversion filter (40) are determined such that highest-intensity light beams emitted from the end of an opening of the organic EL light-emitting portion (60) are incident on the color conversion filter (40) over the entire region of 0=f=360°. Therefore, the opening of the organic EL light-emitting portion (60) is formed narrower than the opening of the color conversion filter (40).
