The invention discloses a light-emitting panel of an in-film injection molding process and a processing method of the light-emitting panel. A light-emitting panel of an in-membrane injection molding process comprises a panel base body, the panel base body comprises a ceramic membrane and a light-shading plastic panel integrally connected with the ceramic membrane, a light-transmitting window is formed in the light-shading plastic panel, and a limiting protrusion partially embedded into the light-transmitting window is arranged on the ceramic membrane; the LED lamp further comprises a light-emitting assembly, the light-emitting assembly comprises a light shield, a light guide part, a light-shielding sealing cover and a light-emitting circuit board, the light guide part comprises a light-transmitting plate and a light-transmitting cover with a downward opening, the light-transmitting plate is connected with the top of the light-transmitting cover, and the lower end of the light-transmitting cover is open; a part of the light-transmitting plate is embedded into the light-transmitting window, and a gap exists between the top face of the light-transmitting plate and the ceramic diaphragm. The shading plastic panel and the ceramic diaphragm are integrally connected, so that the connection stability of the diaphragm and the shading plastic panel is ensured.
