Liquid crystal display device

1. A liquid crystal display device comprising:

a pair of substrates disposed to face each other; an inner sealing material surrounding a non-display region between the pair of substrates; an outer sealing material surrounding the inner sealing material; liquid crystal filled between the inner sealing material and the outer sealing material; and a display region formed in a region where the liquid crystal is filled, wherein

at least a plurality of gate signal lines extending in a first direction and arranged in parallel and a plurality of drain signal lines extending in a second direction and arranged in parallel are formed on a surface of one of the pair of substrates on a liquid crystal side, among the plurality of gate signal lines and the plurality of drain signal lines, the gate signal lines and the drain signal lines which are to be arranged so as to cross the non-display region when they are virtually extended as they are are formed into patterns which bypass the non-display region and partially formed in the forming region of the inner sealing material,

first columnar spacers fixed on any one of the pair of substrates are formed in the forming region of the inner sealing material, the first columnar spacers being formed so as to avoid positions overlapped with intersecting portions of the gate signal lines and the drain signal lines,

the first columnar spacers formed in the forming region of the inner sealing material include those which are formed in a region where the gate signal line and the drain signal line are not formed and those which are formed above the gate signal line or the drain signal line, and

the diameters of the first columnar spacers formed in the region where the gate signal line and the drain signal line are not formed are greater than those of the first columnar spacers formed above the gate signal line or the drain signal line.

2. The liquid crystal display device according to claim 1 , wherein

second columnar spacers fixed on any one of the pair of substrates are formed in the display region.

3. The liquid crystal display device according to claim 2 , wherein

the heights of the first columnar spacers formed in the forming region of the inner sealing material are greater than those of the second columnar spacers formed in the display region.

4. The liquid crystal display device according to claim 2 , wherein third columnar spacers fixed on any one of the pair substrates are formed in the forming region of the outer sealing material.

5. The liquid crystal display device according to claim 4 , wherein

the heights of the third columnar spacers formed in the forming region of the outer sealing material are greater than those of the second columnar spacers formed in the display region.

6. The liquid crystal display device according to claim 2 , wherein

glass fibers or beads are mixed in the outer sealing material.

the diameters of the glass fibers or the beads mixed in the outer sealing material are greater than the heights of the second columnar spacers formed in the display region.

8. The liquid crystal display device according to claim 1 , wherein

common signal lines or capacitor signal lines are each formed between a pair of the gate signal lines adjacent to each other along the gate signal line,

among the common signal lines or the capacitor signal lines, the common signal lines or the capacitor signal lines which are to be arranged so as to cross the non-display region when they are virtually extended as they are formed into patterns which bypass the non-display region and partially formed in the forming region of the inner sealing material, and

the first columnar spacers are formed so as to avoid positions overlapped with intersecting portions of the common signal lines or the capacitor signal lines and the drain signal lines.

9. The liquid crystal display device according to claim 8 , wherein

the first columnar spacers formed in the forming region of the inner sealing material include those which are formed in a region where the gate signal lines, the drain signal lines, and the common signal lines or the capacitor signal lines are not formed and those which are formed above the gate signal lines, the drain signal lines, and the common signal lines or the capacitor signal lines, and

the diameters of the first columnar spacers formed in the region where the gate signal lines, the drain signal lines, and the common signal lines or the capacitor signal lines are not formed are greater than those of the first columnar spacers formed above the gate signal lines, the drain signal lines, and the common signal lines or the capacitor signal lines.
