Abstract
A lower part protection film for an OLED panel is provided. More particularly, a lower part protection film for an OLED panel, having a significantly improved recognition rate of an alignment process, being capable of preventing generation of static electricity through an antistatic treatment, and having excellent adhesion to an OLED panel at the same time, and an organic light-emitting display apparatus including the lower part protection film for an OLED panel are provided.
Claims16
A lower part protection film for an OLED panel, comprising:
- a base-carrier film comprising a base film comprising a first adhesive layer on an upper surface of a first base material and a carrier film comprising a second adhesive layer adhered to a lower surface of the first base material and a second base material adhered to a lower surface of the second adhesive layer;
- and
- a liner film adhered utilizing the first adhesive layer,
- wherein the lower part protection film satisfies both Conditions (1) and (2) below:
- (1) a reflectance of the lower part protection film is 12 to 18% at a wavelength of 400 to 700 nm;
- and
- (2) a reflectance ratio between a reflectance of the liner film and a reflectance of the base-carrier film at a wavelength of 400 to 700 nm is 1:0.3 to 3.0,
- wherein adhesion of the first adhesive layer measured by utilizing a measurement method below is 250 gf/in or higher:
- wherein in the measurement method, the first adhesive layer was adhered to glass, and after 24 hours, adhesion of the first adhesive layer was measured when the first adhesive layer was exfoliated at 180° at a rate of 5 mm per second.
