  • Patent number: 9946116
    Abstract: The present invention relates to a liquid crystal display device that prevents a color shift by allowing two sub-pixel areas to have the same transmittance. A liquid crystal display device according to the present invention includes a data line that includes: a connection portion having a direction of extension perpendicular to that of a gate line; a first portion oriented at a first angle with respect to a direction of extension of the connection portion; and a second portion oriented at a second angle different from the first angle with respect to the direction of extension of the connection portion, and wherein an angle between a rubbing direction of the liquid crystal and the connection portion satisfies ? L = ? 2 - ? 1 2 (where ?L is the angle between the rubbing direction of the liquid crystal and the direction of extension of the connection portion, ?1: the first angle, ?2: the second angle).
