摘要： A liquid crystal display having improved retardation plate is described. In the liquid crystal display, at least one of two panel plates has a polarizer placed on an outer side which is opposite to a liquid crystal layer and a quarter wavelength retardation plate between a substrate glass and the polarizer. The quarter wavelength retardation plate is composed of two retardation films including a half wavelength and a quarter wavelength retardation film. A slow axis of a half λ film which is adjacent to the polarizer makes an angle of Θ1 with a transmissive axis of the polarizer and that of a quarter λ film which is adjacent to the substrate glass makes an angle of Θ2 where Θ2=2×Θ1±45 degree. The retardation films are single-axial films. The specific angle Θ1 is one of degree values (15, 75, 105, and 165). In a transmissive type liquid crystal display, a structure of the other panel plate is similar to that of one panel plate and combination to the values (Θ1, Θ2, Θ3, Θ4) is one selected from the group consisting of combinations (15, 75, 165, 105), (75, 15, 105, 165), (105, 165, 75, 15), and (165, 105, 15, 75).

摘要： Disclosed is a transmissive and reflective type LCD. In the LCD, a second substrate faces a first substrate. A liquid crystal layer is formed between the first substrate and the second substrate. A first polarizing plate is formed on an outer surface of the first substrate. A second polarizing plate is formed on an outer surface of the second substrate. A backlight is arranged for irradiating incident light onto the polarizing plate. A transparent transflective film is arranged between the first polarizing plate and the backlight for partially reflecting and partially transmitting the incident light. The transparent transflective film includes at least a first layer and a second layer, the first and second layers having different refractivity indexes from each other and are alternatively stacked. By a restoring process occurring between the transflective film and the backlight, a predetermined amount of the incident light is transmitted through the transflective film repeatedly, so that transmissivity and light efficiency are enhanced.
