A barrier film which can effectively protect an organic EL device, an efficient method for producing the barrier film, and a light-emitting display exhibiting excellent durability in which a non-emission area such as the dark spot occurs to only a small extent are provided. A method for producing a barrier film for light-emitting displays including a glass material containing three or more components, the barrier film being formed by a vapor deposition method. A light-emitting display including a supporting substrate 1, an emitting layer 2, and the barrier film 3 produced by the method. The barrier film can be produced with a target containing 50 to 90 wt% of silicon oxide, 5 to 20 wt% of boron oxide and 1 to 10 wt% of aluminum oxide by sputtering method.
