PROBLEM TO BE SOLVED: To provide a light shielding reflective tape which includes superior light shielding property and reflectivity although being a thin type, and hardly includes a decrease in visibility due to protrusion of an adhesive tape at high temperature and a decrease in visibility due to distortion of an optical film, even pasted between an LCD panel and a backlight housing. SOLUTION: Protrusion to an image display area at high temperature can be suppressed and further a decrease in visibility due to distortion of the optical film can be suppressed by the light shielding tape which includes a support body having a light reflective layer and a light shielding layer, and an adhesive layer provided on at least one surface of the support body, and is characterized in that the light reflective layer includes a layer formed of a biaxially oriented white resin film, a maximum value of a loss tangent of the biaxially oriented white resin film obtained through dynamic viscoelasticity spectrum measurement at a frequency of 0.1 Hz is within a range of 105 to 150°C, the thickness is 6 to 30μm, a loss tangent of the adhesive layer in dynamic viscoelasticity spectrum at 85°C and at a frequency of 1 Hz is 0.4 to 0.8, and the total thickness is 20 to 100μm.
