(57) [Summary] [Problem] To be transparent without coloring in the visible light range, and to effectively shield all of electromagnetic waves, heat rays and near infrared rays emitted from a plasma display panel, to increase the temperature of the panel surface and to increase home electric appliances. Provided is an optical film that can prevent a product from malfunctioning and can be easily attached to the front of the panel. SOLUTION: A metal thin film layer 11 having a visible light transmittance of 50% or more and cutting electromagnetic waves and heat rays on a transparent film substrate 10 and an inorganic or organic transparent coat layer 12A, 12B as an upper layer and / or a lower layer thereof. And a near-infrared reflective film 2 having a solidified layer 21 of a polymer liquid crystal that reflects near-infrared light to form a composite film 102, and a composite film 102 is provided on one side of the composite film 102. 90 ° against glass 100 peel adhesion An optical film X1 is formed by providing a transparent pressure-sensitive adhesive layer 3 having a width of １，1,500 g / 20 mm. |
