Liquid crystal panel and method for fabricating the same, display device

A method for fabricating a liquid crystal panel, the liquid crystal panel having a plurality of pixel regions, and the method comprising steps of:

• preparing a first substrate and a second substrate arranged oppositely, and a liquid crystal layer provided between the first substrate and the second substrate, wherein the second substrate, the liquid crystal layer and the first substrate are provided in a light emergent direction of the liquid crystal panel in this order;
• wherein, for each pixel region, a surface of the first substrate close to the liquid crystal layer is formed to have a first cambered surface, and a surface of the second substrate close to the liquid crystal layer is formed to have a second cambered surface, such that the first cambered surface protrudes towards the liquid crystal layer, the second cambered surface is recessed in a direction away from the liquid crystal layer, axes of the first cambered surface and the second cambered surface coincide with each other, and 0° viewing angle point of the pixel region is located on the axes,
• the first cambered surface and the second cambered surface are each partial spherical surfaces and are formed such that an optical path length of a first light ray from the second cambered surface to the first cambered surface equals to an optical path length of a second light ray from the second cambered surface to the first cambered surface,
• the first light ray being a light ray that is emitted by the pixel region to which the first cambered surface and the second cambered surface belong, has a first angle with respect to a first straight line perpendicular to a light emergent surface of the liquid crystal panel and passing through a center point of the pixel region to which the first cambered surface and the second cambered surface belong, and reaches a point on the first straight line, and
• the second light ray being a light ray that is emitted by the pixel region to which the first cambered surface and the second cambered surface belong, has a second angle different from the first angle with respect to the first straight line, and reaches the point on the first straight line.
