| Zusammenfassung: | The invention provides a display which comprises an optical lens and a light valve. The optical lens comprises a first lens, a second lens and a third lens, wherein the first lens, the second lens andthe third lens are sequentially arranged from the light exiting side to the light incident side. The light valve is arranged on the light incident side. The light valve provides an image beam. The optical lens is used to receive the image beam. The image beam forms a stop on the light exiting side. The stop has the smallest cross-sectional area of the beam contraction of the image beam. The imagebeam has OPD on the active surface of the light valve, wherein the range of OPD is that -2.0 lambda |
