Abstract
Between a pair of mother substrates, spaces are defined by a seal. The pair of mother substrates is cut to cut out cells. The seal is arranged to fill a region between adjacent spaces. On the seal, a low moisture-permeable layer made of a material that is harder and has lower moisture permeability than the seal is laminated in the region between the adjacent spaces. On at least one of the pair of mother substrates, a pair of projecting stripe portions extending along a length of the seal and arranged at an interval is formed in the region between the adjacent spaces at a position overlapping with the seal and the low moisture-permeable layer. In a step of cutting the pair of mother substrates, together with the pair of mother substrates, the seal and the low moisture-permeable layer are cut between the pair of projecting stripe portions.
