Stereoscopic image display |
摘要 |
A stereoscopic image display includes a display panel, a first polarizing plate positioned on an upper surface of the display panel, a patterned retarder positioned on the first polarizing plate, a first cellulose triacetate (TAC) film positioned on the patterned retarder, a second polarizing plate positioned on a lower surface of the display panel, and a second TAC film positioned under the second polarizing plate. |

1. A stereoscopic image display comprising:
a display panel; a first polarizing plate positioned on an upper surface of the display panel; a retardation film positioned between the display panel and the first polarizing plate; a patterned retarder positioned and directly formed on the first polarizing plate; a first cellulose triacetate (TAC) film positioned on the patterned retarder; a second polarizing plate positioned on a lower surface of the display panel; and a second TAC film positioned under the second polarizing plate, wherein the retardation film is represented by a retardation value Rin and a refractive index nz of a thickness direction as indicated in the following Equations:nz=nx-nznz-ny Rin=(nx−ny)d where ‘nx’ is a refractive index of an axis having a maximum refractive index in the in-plane direction, ‘ny’ is a refractive index of a vertical direction of the refractive index nx in the in-plane direction, ‘nz’ is a refractive index of a thickness direction, and ‘d’ is a thickness of the retardation film, and wherein the retardation film has a relationship of nx>nz>ny with respect to the refractive index, where 0<nz<1. |
