Abstract

A liquid crystal display device includes a liquid crystal display panel which includes an array substrate including a pixel electrode, a gate line extending in a first direction and crossing the pixel electrode, and a data line extending in a second direction substantially perpendicular to the first direction, an opposing substrate including a common electrode in which a slit extending in the first direction and overlapping the gate line is defined, and a liquid crystal layer between the array substrate and the opposing substrate, and a light diffusion film which is disposed on the liquid crystal display panel and includes a plurality of low-refractive line members which respectively extends in the first direction and arranged in the second direction.

Dependent claims

A liquid crystal display device comprising:

a liquid crystal display panel comprising:
an array substrate comprising:
a pixel electrode;
a gate line extending in a first direction and crossing the pixel electrode;
and
a data line extending in a second direction substantially perpendicular to the first direction;
an opposing substrate comprising a common electrode in which a slit extending in the first direction, overlapping the gate line, and having a length longer than a length of the pixel electrode along the first direction of the gate line in a plan view is defined;
and
a liquid crystal layer between the array substrate and the opposing substrate;
and
a light diffusion film which is disposed on the liquid crystal display panel and comprises a plurality of low-refractive line members which respectively extends in the first direction and is arranged in the second direction,
wherein an entire width of the slit is less than an entire width of the gate line in the second direction.
