NOVELTY - A transparent film (21) contains acrylic copolymer, an epoxy resin and an epoxy hardening agent, and has thickness of 1-200 mu m. The transparent film has mass reduction rate of 0-8% after thermosetting at 180 degrees C for 1 hour, and total light transmittance of 77-100% with respect to light having wavelength of 400 nm after thermosetting at 150 degrees C for 1 hour. The adhesive force of transparent film with respect to polyimide film before thermosetting and after thermosetting at 150 degrees C for 1 hour is 0.2-15 N/m and 50-10000 N/m, respectively.    USE - Transparent film is used for laminated film and inorganic particle clamped film for panel for display (all claimed), light emitting diode and solar cell. Uses include but are not limited to liquid crystal display, organic electroluminescent display, electrochromic display, twisting ball display, electro granular fluid display, electrophoresis display, etc.    ADVANTAGE - The transparent film has high adhesion strength and reduced coloring.    DETAILED DESCRIPTION - A transparent film (21) contains acrylic copolymer, an epoxy resin and an epoxy hardening agent, and has thickness of 1-200 mu m. The amount of epoxy resin with respect to 90 parts mass of acrylic copolymer is 1-25 parts mass. The amount of hardening agent is 0.4-6 times of epoxy equivalent of epoxy resin. The transparent film has mass reduction rate of 0-8% after thermosetting at 180 degrees C for 1 hour, and total light transmittance of 77-100% with respect to light having wavelength of 400 nm after thermosetting at 150 degrees C for 1 hour. The adhesive force of transparent film with respect to polyimide film before thermosetting and after thermosetting at 150 degrees C for 1 hour is 0.2-15 N/m and 50-10000 N/m, respectively. INDEPENDENT CLAIMS are included for the following:    (1) laminated film, which has the transparent film clamped between primary and secondary films. The storage elastic modulus of transparent film at 25 degrees C is 30-1000 MPa. The peeling strength between primary film and transparent film is 0.2-0.6 N/m. The peeling strength between secondary film and transparent film is 0.1-0.4 N/m. The peeling strength between primary film and transparent film is more than peeling strength between secondary film and transparent film;    (2) inorganic particle-clamped film, which has inorganic particles clamped by the transparent film. The inorganic particles have mass average particle diameter of 0.01-10 mu m. The absolute value of real portion or imaginary portion of refractive index of clamped film at 400 nm is 1.6-5.6; and    (3) panel for display, which has the transparent film, and laminated film or inorganic particle-clamped film. The panel has total light transmittance of 85-100% and 0-40% before thermosetting and after thermosetting, respectively, and linear transmittance of 75% or more.
