1. A liquid crystal display, comprising:
a plurality of pixels arranged in a matrix, wherein each pixel of the plurality of pixels comprises:
a first substrate;
a second substrate;
a first electrode on an opposing face of the first substrate that faces the second substrate;
a second electrode on an opposing face of the second substrate that faces the first substrate;
a color filter layer between the first substrate and the first electrode, the color filter layer providing a plurality of uneven portions above the first substrate;
a liquid crystal layer between the first electrode and the second electrode, wherein the liquid crystal layer includes a plurality of liquid crystal molecules;
a plurality of branch convex portions arranged in a plane, wherein the plurality of branch convex portions are convex when viewed from a direction perpendicular to the plane, and extend from a central region of the first electrode to a periphery of the first electrode; and
a plurality of concave portions in the plane, individual concave portions of the plurality of concave portions are arranged to alternate with individual branch convex portions of the plurality of branch convex portions,
wherein the plurality of branch convex portions includes (i) a first subset of the branch convex portions that extends from a first side of a stem convex portion on an axis and (ii) a second subset of the branch convex portions that extends from a second side of the stem convex portion on the axis, the first side of the stem convex portion being different from the second side of the stem convex portion, the first and second subsets of the branch convex portions extending from the stem convex portion to a same side of the respective pixel,
wherein a width of each of the plurality of branch convex portions and each of the plurality of concave portions is 1 μm to 25 μm, and a width of the stem convex portion is 2×10−6 m to 2×10−5 m, and
wherein a width of a portion of the stem convex portion on the first electrode becomes narrower toward a tip portion of the stem convex portion.
