ABSTRACT:
A liquid crystal display device comprising a first substrate, a second substrate, a liquid crystal layer and a shading film is provided. The first substrate includes a display region and a non-display region. The liquid crystal layer is sandwiched between the first substrate and the second substrate. The shading film is located between the first substrate and the liquid crystal layer covering the non-display region. With the shading film covering the entire non-display region, the problem of light leakage from the edge of the display device is resolved.
