Abstract: The present invention provides a cleaning method by which it is possible to prevent deformation of a film formation mask (31). While the film formation mask (31) disposed between a shower head (4) and a susceptor (3) within a chamber (2) is cooled, a cleaning gas made into plasma, which cleaning gas reacts with a reaction product (32) deposited on a surface of the film formation mask (31), is blown on the film formation mask (31).

Abstract: A display device includes: a plurality of organic layers each made of an organic material and each having a predetermined modulus of elasticity and a predetermined thickness; and a plurality of inorganic layers each made of an inorganic material and each having a predetermined modulus of elasticity and a predetermined thickness. The plurality of organic layers and the plurality of inorganic layers are stacked together to constitute a device body which forms the display device. A quotient obtained by dividing the sum of flexural rigidities of the plurality of inorganic layers by the sum total of the sum of flexural rigidities of the plurality of organic layers and the sum of the flexural rigidities of the plurality of inorganic layers is 0.78 or higher and 1 or lower.
