Abstract:
An organic EL display device (10) includes: an insulating substrate (20); a first planarizing film (21) formed on the insulating substrate (20) and made of a resin; a first electrode (13) formed on the first planarizing film (21); an organic EL layer (17) formed on the first electrode (13); a second electrode (14) formed on the organic EL layer (17); and a second planarizing film (22) formed between the first electrode (13) and the first planarizing film (21), and covering the first planarizing film (21). The second planarizing film (22) is made of a resin having a lower hygroscopic property than the resin forming the first planarizing film (21).
