The above object is achieved by a liquid crystal display panel comprising: an LCD module; A backlight unit for emitting light to the LCD module; A film layer for adjusting characteristics of light provided from the backlight unit; And a touch sensor module coupled to one side or both sides of the film layer.

The film layer may include at least one of a polarizing film layer, an optical film layer, an ITO film layer, and an OCA film layer.

The film layer may include a diffusion film layer inside the backlight unit.

The touch sensor module may be disposed between the ITO film layer and the OCA film layer.

The touch sensor module may be coupled to the upper and lower ends of the ITO film layer, respectively.

The coating layer may be bonded to one end of the OCA film layer.

According to the touch sensor integrated liquid crystal display panel according to the present invention, the manufacturing yield can be increased.

In addition, according to the touch sensor integrated liquid crystal display panel according to the present invention, multi-touch can be easily implemented.

According to the touch sensor integrated liquid crystal display panel of the present invention, the touch sensor module can be easily applied to a large or flexible panel.
