The sealed body described in the modification example of this embodiment includes the high-reflectivity region 105a and the low-reflectivity region 105b which are placed in consideration of the integral intensity of the emitted energy ray (see FIG. 2C). Specifically, the high-reflectivity region 105a is provided in the portion where the integral intensity of the emitted energy ray becomes low (for example, the portion irradiated with the end portion of the laser beam spot), and the low-reflectivity region 105b is provided in the portion where the integral intensity of the emitted energy ray becomes high (for example, the portion irradiated with the center portion of the laser beam spot). With such a structure, the sealant 131 in a portion through which the end portion of the laser beam passes (i.e., a portion irradiated with the laser beam for a short time) is irradiated with not only light entering the sealant 131 from the second substrate 102 side but also light reflected by the high-reflectivity region 105a; thus, the unevenness of the integral intensity can be compensated for. As a result, the size of the outer shape of the sealed body is reduced and sealing is uniformly performed in the sealed body; thus, the sealed body can have high reliability.
