The present invention provides a pixel signal line module of a liquid crystal display, wherein a plurality of sub-pixels are alternately arranged in delta form on a liquid crystal display panel. A plurality of signal scan lines are used to cover and connect each transversally arranged pixel. A plurality of longitudinal data signal lines alternately shift leftwards and rightwards according to the checkered arrangement of the longitudinal sub-pixels so as to connect the sub-pixels in two adjacent longitudinal rows together in indented way. The present invention lets the signal lines be not limited by the arrangement of sub-pixels, and has the advantages of enhanced resolution, larger signal line's width, reduced impedance, and less signal distortion.
