According to embodiments of the present invention, there are provided a sub-pixel structure of a thin film transistor liquid crystal display and a liquid crystal display. The sub-pixel structure comprises: a gate line, a data line, a thin film transistor, a sub-pixel electrode, and a common electrode, which are formed on an array substrate, wherein a liquid crystal electric field in a first domain and a liquid crystal electric field in a second domain, which are located on both sides of the gate line, respectively, are created between the sub-pixel electrode and the common electrode, and the angle between the direction of the liquid crystal electric field in the first domain and the direction of the liquid crystal electric field in the second domain is larger than 0° and smaller than 180°.
