PURPOSE: A screen of a color braun tube is provided to prevent a metal reflective film from being arisen by embedding a low temperature decomposable polymeric particle into an organic film in order to easily exhaust a gas. CONSTITUTION: The screen of color braun tube comprises a plurality of light absorption layers(301) formed on a panel(300) at a predetermined distance; fluorescent films(304R,304G,304B) including fluorescent material formed between the light absorption layers(301); an organic film(305) including a low temperature decomposable polymeric particle(401) formed on the fluorescent films(304R,304G,304B); and a metal reflective film formed on the organic film(305). The temperature of the low temperature decomposable polymeric particle(401) is lower than that of the organic film(305). The average grain size of the low temperature decomposable polymeric particle(401) is 3-10μm.
