Abstract

PURPOSE:To improve the heat resisting property and the humidity resisting property, by sticking a dyestuff-polarized plate on both surfaces of a TN-type liquid crystal display element, and also placing a semitransmittable reflecting plate which has covered one surface of a hat-resistive plastic sheet with an organic film containing a reflecting material, on the reverse side. CONSTITUTION:This display device is provided with an upper substrate 1, a lower substrate 2, a sealing agent 3, a liquid crystal 4, an upper polarized plate 5, adhesive agents 6, 7 and 9, a lower polarized plate 8, a heat- and humidity-resistance supporting plate 31, a semitransmittable reflecting film 32, a semitransmittable reflecting plate 33 consisting of this supporting plate 31 and the reflecting film 32, and a light diffusing surface 34. The supporting plate 31 is made of a plastic sheet having a high heat-resisting property and is 0.05-0.25mm. in thickness, and the semitransmittable reflecting film 32 is a film of an organic matter containing a reflecting material. When this semitransmittable reflecting film 32 is applied onto the supporting plate 31 so as to be about 20-200mu and is dried so that it becomes the semitransmittable reflecting plate 33 of 0.1-0.3mm. in total thickness, that which has 45-65% reflectance and 1.0-2.0% transmissivity is obtained.
