Abstract
The light-emitting device includes a light-emitting element chip; a package having a first recessed portion thereon, in which the light-emitting chip is disposed; a transparent flexible member covering at least the recessed portion; and a transparent rigid member disposed on or above the transparent flexible member. The package has at least a first front surface extending at least outwardly above the first recessed portion; a second front surface extending outwardly above the first front surface; and a third surface as the outside of the package extending outwardly above the second front surface. The rigid member is disposed in the outline of the second front surface with at least three points of contact. The flexible member is continuously provided along the first front surface, the second front surface and the back surface of the rigid member. This light-emitting device is capable of improved reliability without deteriorating its optical characteristics.
