Abstract

A liquid crystal display includes a liquid crystal provided between a first layer and a second layer. The first layer and the second layer may be in a substantially parallel direction to each another. Spacers may be provided in the liquid crystal to keep the first layer and the second layer spaced apart from each other. Electrode layers may include structural elements operable to prevent the spacers from moving through the liquid crystal in the substantially parallel direction. The display may include a first electrode layer and a second electrode layer having one or more gaps defining an electrode structure including electrodes to control the display.

Claims (18)

1. A liquid crystal display, comprising:

a liquid crystal provided between a first layer and a second layer, the first layer and the second layer being in a substantially parallel direction to each another;

one or more spacers being provided in the liquid crystal to keep the first layer and the second layer spaced apart from each other; and

one or more electrode layers comprising one or more structural elements operable to prevent the spacers from moving through the liquid crystal in a said substantially parallel direction, wherein

a first said electrode layer and a second said electrode layer further comprises one or more gaps defining an electrode structure comprising electrodes to control the display.

2. The display according to claim 1 , wherein the display comprises a passive liquid crystal display wherein the gaps define one or more display cells.

3. The display according to claim 2 , wherein the structural elements have a length substantially lesser than that of the display cells.

4. The display according to claim 2 , wherein the display comprises a double layer super twisted nematic (DSTN) display, and further comprises any one or both of: an active liquid crystal display; and a passive liquid crystal display according to claim 2 .

5. The display according to claim 1 , wherein the display is an active liquid crystal display and wherein the gaps defining the electrodes are used to address pixels.

6. The display according to claim 5 , wherein the structural elements have a length substantially lesser than that of a said pixel.

7. The display according to claim 5 , wherein the display comprises a double layer super twisted nematic (DSTN) display, and further comprises any one or both of: an active liquid crystal display according to claim 5 ; and a passive liquid crystal display.

8. The display according to claim 1 , wherein the structural elements do not change the electrode structure.

9. The display according to claim 1 , wherein the structural elements are formed by one or more elongated trenches.

10. The display according to claim 9 , wherein the trenches have a width substantially lesser than a diameter of a said spacer.

11. The display according to claim 1 , wherein the spacers are formed by a plurality of substantially round elements.

12. The display according to claim 11 , wherein one or more of the spacers have a diameter of 4 to 6 micrometers (μm).

13. The display according to claim 1 , wherein the structural elements are provided in one of: a randomized format; and a quasi randomized format.

14. The display according to claim 1 , wherein any one of the first layer and the second layer of the display further comprises a liquid crystal alignment sublayer comprising rubbing lines, and wherein the structural elements are provided at an angle with respect to said rubbing lines.
