PURPOSE: To widen a visual field angle and to display images with a high contrast by providing the above element with polarizing plates arranged on at least either side of a liquid crystal cell and plural thin films which are laminated on the outside surfaces of these polarizing plates and vary in refractive index. CONSTITUTION: This liquid crystal display element is composed of a pair of transparent substrates 11, 12, the liquid crystal cell 19 which is composed of liquid crystals 13 enclosed between these substrate substrates 11 and 12, a pair of the polarizing plates 14, 15 which are arranged across the liquid crystal cell 19 and low reflection films (antireflection films) 16, 17 which are arranged on the outside surfaces of the polarizing plates 14, 15. TFTs 21 as active elements and pixel electrodes 22 are arranged in a matrix form on the one transparent substrate 11 and the oriented film 23 is arranged thereon. These low reflection films 16, 17 are formed by alternately laminating plural TiO2 films and plural SiO2 films. Since the TiO2 and the SiO2 vary in the refractive index, the refraction and reflection of light arise at the boundaries between the TiO2 films and the SiO2 films and the reflection of incident light is lessened. |
