▎ 摘  要

NOVELTY - Protective film comprises a substrate (140), and a light shielding layer (150) disposed in an edge portion of one surface of the substrate, where the light shielding layer comprises a first layer (152) on an edge of one surface of the substrate and a second layer (154) on the first layer. The first layer comprises a first portion (152a) being continuously disposed along the edge portion of the substrate and a second portion (152b) being discontinuously disposed along the edge portion of the substrate. USE - Protective film used in OLED display apparatus (claimed). ADVANTAGE - The protective film ensures improvement in the printing quality of the light shielding layer on the substrate by preventing or reducing the occurrence of a crack caused during the folding process, improving the adhesive strength of the light shielding layer, and thus improving structural reliability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a display apparatus, which comprises a display panel, and a protective film disposed on the display panel. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of the protective film. 140Substrate 150Light shielding layer 152, 154Layers 152a, 152bPortions DADisplay area
