Spacer Patents (Class 349/155)
  • Patent number: 9871088
    Abstract: When a hollow structure in which a light-emitting element is provided between a pair of substrates is used in order to prevent oxygen or moisture from reaching the light-emitting element, light leakage to an adjacent pixel easily occurs as compared to a structure in which a space between a pair of substrates is filled with a resin such as an adhesive. In order to reduce light leakage to an adjacent pixel in the hollow structure, a light-blocking spacer is formed over a partition to keep the distance between the pair of substrates uniform. The cross-sectional shape of the light-blocking spacer is a trapezoid having a lower side shorter than an upper side.
