ABSTRACT:
A color liquid crystal display panel includes a first substrate having data lines and scan lines arranged in a matrix, a second substrate having four-color filter segments to provide four sub-pixels forming a pixel, a frame-shaped sealing material through which the first and second substrates are bonded together, and a liquid crystal sealed in a gap surrounded by the first and second substrates and the sealing material. The data lines and the scan lines are drawn out of the sealing material and arranged as inspection data lines having a predetermined length. Among the inspection data lines LR, LG, LB, LCcorresponding to the four-color filter segments, at least one pair of the inspection lines for two colors sandwich one inspection data line for one color and have identical lengths. According to the above-described configuration, it is possible to provide a color liquid crystal display panel such that, even when the number of color filter segments per pixel is increased, the space where the inspection lines are provided to inspect the wiring condition on the display panel is not increased.
