  • Patent number: 10197850
    Abstract: A virtual curved surface display panel and a display device are provided. By using the light splitting principle of the grating structure, the imaging heights of the grating structures are designed to be symmetrically distributed with respect to a vertical symmetry axis of a display surface of the flat display panel. In the grating structures on the same side of the symmetry axis, the imaging heights of the respective grating structures having the same distance from the vertical symmetry axis are the same, and the imaging heights of the respective grating structures having different distances from the vertical symmetry axis are different from each other. By setting the imaging heights of the grating structures, the image distances of the pixels in the flat display panel are different so that the images of the plurality of pixels constitute a curved surface.

  • Patent number: 10197857
    Abstract: The present invention prevents the shaving of an alignment film caused by a columnar spacer in a liquid crystal display device of an IPS method using photo-alignment. A plinth higher than a pixel electrode is formed at a part where a columnar spacer formed over a counter substrate touches a TFT substrate. When an alignment film of a double-layered structure is applied over the pixel electrode and the plinth, the thickness of the alignment film over the plinth reduces by a leveling effect. When photo-alignment is applied in the state, a photodegraded upper alignment film over the plinth disappears and a lower alignment film having a high mechanical strength remains. As a result, it is possible to prevent the shaving of the alignment film.
