Abstract
The present invention relates to the field of display technologies, and discloses a raster, a display apparatus and a method of manufacturing the raster. The raster comprises a first substrate and a second substrate arranged to be opposed to each other, a surface of the first substrate facing the second substrate is provided with a plate electrode thereon, a surface of the second substrate facing the first substrate is provided thereon with a plurality strip electrodes arranged to space apart from each other. A spacer wall is arranged to correspond to each strip electrode and located between the first substrate and the second substrate, the spacer wall comprises a conductive protrusion electrically connected with the strip electrode, and a hydrophilic-hydrophobic conversion material layer covering the conductive protrusion. Filled between every two adjacent spacer walls are liquid layers including a polar liquid layer and a non-polar liquid layer. With the technique solution of the present invention, an angle of view of the raster may be increased, and a cost of the raster reduced.
