| abstract | (57) [Summary] [Structure] The diffraction grating 16 is formed on the counter electrode 15. Further, the thin film 18 is formed on the counter electrode 15 above the source signal line 14. The ratio d / p between the height d of the diffraction grating 16 and the bitch p is set to 1/3 or more. When a voltage is applied to the pixel electrodes 13, the refractive index n of the polymer-dispersed liquid crystal 17 becomes the ordinary refractive index n o. Refractive index n k of the n o diffraction grating 16 If the voltage is applied to the liquid crystal layer 17, the diffraction grating disappears. When the voltage on the pixel electrode 13 is not applied, approximately when the refractive index n of the polymer-dispersed liquid crystal 17 to the extraordinary refractive index of the liquid crystal and n e (2n o + n e ) / 3, a refractive index difference between the refractive index n k of the diffraction grating 16 and the liquid crystal layer 17 occurs, and the light incident on the liquid crystal panel is diffracted. [Effect] Since no polarizing plate is used, high brightness of the display screen can be realized. Further, since the liquid crystal layer is provided with the diffraction grating, image display with high contrast can be realized. |
