有機EL素子用透明電極板および有機EL素子
Document Type and Number:
Japanese Patent JP4531913
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an organic EL element with good durability and high reliability by preventing generation of a defect peculiar to organic EL element, such as generation of a dark spot. SOLUTION: A metal oxide transparent electrode layer is formed on a thermoplastic substrate. The metal oxide transparent electrode layer with which the thermoplastic resin substrate fills the requirements for the following (a)-(c) is used. (a): surface evenness of not more than 4 nm with a 10-point average roughness Rz based on JIS B0601; (b): low water absorption of not more than 0.02 W% in saturated water absorption (JIS K7209) by Karl Fischer method (JIS K0068); and (c): the difference ΔT(=Tmg-Twp) between intermediate-point glass transition temperature Tmg and peak endothermic temperature Twp of thermoplastic resin constituting the substrate, based on JIS K7121 to be 20 deg.C<ΔT<100 deg.C.
