Claims

[Scope of utility model registration request]

A light source tube whose light emitting surface has a plurality of light emitting chambers each coated with phosphor on the inner surface, and an electrode chamber hermetically sealed to the light source tube so as to form a discharge space communicating with each light emitting chamber. , a plurality of anodes respectively arranged in each light emitting chamber, and one common cathode pinched by a lead wire in the electrode chamber, and a discharge gas is sealed in the discharge space, and a desired anode and a common cathode are provided. In a fluorescent lamp for a display element, in which when a voltage that causes a discharge is applied between the common cathode and the phosphor in the light emitting chamber in which the anode that is generating the discharge is disposed, the phosphor emits light at the pinched portion of the common cathode. A fluorescent lamp for a display element, characterized by forming an uneven surface.
