Color liquid crystal display panel
View Patent ↗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 L R , L G , L B , L C corresponding 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.
1. A color liquid crystal display panel comprising:
a first substrate having data lines and scan lines arranged in a matrix;
a second substrate having four-color filter segments including color for red (R), green (G), blue (B), and cyan (C) to provide four sub-pixels forming a pixel;
a frame-shaped sealing material through which said first and second substrates are bonded together; and
a liquid crystal sealed in a gap surrounded by said first and second substrates and said sealing material;
said data lines being drawn out of said sealing material and arranged as inspection data lines having a predetermined length, and
among said inspection data lines corresponding to said four-color filter segments, at least one pair of said inspection lines for two colors sandwiching one inspection data line for one color and having identical lengths, and the inspection data lines have three different lengths.
2. The color liquid crystal display panel according to claim 1 , wherein a pair of said inspection data lines are positioned between a longer inspection data line and a shorter inspection data line than any other data lines.
3. The color liquid crystal display panel according to claim 1 , wherein a pair of said inspection data lines are longer than any other inspection data lines.
4. The color liquid crystal display panel according to claim 1 , wherein a pair of said inspection data lines are shorter than any other inspection data lines and close to said sealing material.
5. The color liquid crystal display panel according to claim 1 , wherein a pair of said inspection data lines are longer than any other inspection data lines and another pair of said inspection data lines are shorter than any other inspection data lines.
6. The color liquid crystal display panel according to claim 1 , wherein each of said inspection data lines is provided with an inspection terminal to be in contact with an inspection probe.
7. The color liquid crystal display panel according to claim 1 , wherein each of said inspection data lines is provided with a mounting terminal for mounting a semiconductor element for driving a liquid crystal.
