Light emitting device and method for fabricating the same

A light emitting device, comprising:

• a package body comprising a resin and a cavity which is provided with a bottom face and inner walls surrounding the bottom face, the package body including a front surface including an opening configured to be a top face of the cavity, and a back surface disposed on an opposite side of the package body with respect to the front surface, the back surface including a recess recessed toward the front surface, the inner walls including a first inner wall, a second inner wall facing the first inner wall, a third inner wall, and a fourth inner wall facing the third inner wall,
• a light emitting element disposed in the cavity, and
• a lead frame including a first portion and a second portion, the first portion supporting a lower portion of the light emitting element and electrically connected to the light emitting element, the second portion having a flat portion extended from the first portion outside the package body,
• wherein a first angle between the first inner wall of the cavity and the second inner wall of the cavity is different from a second angle between the third inner wall of the cavity and the fourth inner wall of the cavity,
• wherein an angle of inclination of the first inner wall of the cavity with reference to the bottom face of the cavity is different from an angle of inclination of the third inner wall of the cavity with reference to the bottom face of the cavity,
• wherein a distance from the front surface to the bottom face is no greater than 450 micro meters,
• wherein the package body includes a side surface extending between the front surface and the back surface on a lateral side of the package body, the side surface having a first side surface disposed adjacent to the cavity in a direction perpendicular to the front surface and a second side surface extended from the first side surface, and the second side surface of the package body being inclined with reference to an axis perpendicular to the front surface,
• wherein an angle of inclination of the first side surface of the package body with reference to the front surface is different from an angle of inclination of the second side surface of the package body with reference to the front surface,
• wherein the lead frame includes a portion provided between the first side surface of the package body and the second side surface of the package body, and
• wherein at least one of the first inner wall, the second inner wall, the third inner wall, or the fourth inner wall includes two or more inclined surfaces with reference to the bottom face of the cavity.
