Abstract

Y-scribe lines are successively formed substantially in parallel in a first direction of a work that constitutes a display device. An X-scribe line is formed in a second direction that intersects the first direction of the work. The X-scribe line is formed between the Y-scribe lines and is spaced apart from the Y-scribe lines.

Claims

1. A method of manufacturing a display device comprising:

a step of forming a first scribe line in a first direction of an insulating substrate that forms the display device; and

a step of forming a second scribe line in a second direction that intersects the first direction of the insulating substrate,

wherein the second scribe line is formed such that the second scribe line is spaced apart from the first scribe line that is formed in the preceding step.

2. The method of manufacturing a display device, according to claim 1, wherein the step of forming the first scribe line includes a step of forming a third scribe line that is parallel to the first scribe line, and

the second scribe line is formed such that the second scribe line is spaced apart from the third scribe line that is formed in the preceding step.

3. The method of manufacturing a display device, according to claim 2, wherein the second scribe line has a start point on the first scribe line side and has an end point on the third scribe line side, and

each of a shortest distance between the start point of the second scribe line and the first scribe line and a shortest distance between the end point of the second scribe line and the third scribe line is between 0.1 mm and 1.0 mm.

4. The method of manufacturing a display device, according to claim 2, wherein the second scribe line has a start point on the first scribe line side and has an end point on the third scribe line side, and

a shortest distance between the start point of the second scribe line and the first scribe line is equal to or less than a shortest distance between the end point of the second scribe line and the third scribe line.

5. A method of manufacturing a display device comprising:

a step of forming an effective display section, which forms the display device, on an insulating substrate;

a step of successively forming a first scribe line and a third scribe line substantially in parallel in a first direction of the insulating substrate such that the effective display section is sandwiched between the first scribe line and the third scribe line; and

a step of successively forming a second scribe line and a fourth scribe line in a second direction, which is substantially perpendicular to the first direction of the insulating substrate, such that the effective display section is sandwiched between the second scribe line and the fourth scribe line,

wherein the second scribe line and the fourth scribe line are formed between the first scribe line and the third scribe line that are formed in the preceding step, and are spaced apart from the first scribe line and the third scribe line.

6. A method of manufacturing a display device, wherein an insulating substrate that forms the display device is scribed, the method comprising:

a step of lowering a scribe member, pressing the scribe member on a first start point on the insulating substrate under a predetermined load, and scribing the insulating substrate from the first start point to a first end point in a first direction, thereby forming a first scribe line; and

a step of lowering the scribe member, pressing the scribe member on a second start point, which is spaced apart from the first scribe line, under a predetermined load, and scribing the insulating substrate from the second start point to a second end point in a second direction that intersects the first direction, thereby forming a second scribe line that is spaced apart from the first scribe line.

7. The method of manufacturing a display device, according to claim 6, further comprising:

a step of moving the scribe member beyond the first scribe line, lowering the scribe member on a third start point that is collinear with the second scribe line, pressing the scribe member on the third start point under a predetermined load, and scribing the insulating substrate from the third start point to a third end point in the second direction, thereby forming a third scribe line.

8. The method of manufacturing a display device, according to claim 6, further comprising:

a step of moving the scribe member beyond the first scribe line, lowering the scribe member on a third start point that is non-collinear with the second scribe line, pressing the scribe member on the third start point under a predetermined load, and scribing the insulating substrate from the third start point to a third end point in the second direction, thereby forming a third scribe line that is parallel to the second scribe line and is spaced apart from the first scribe line.

9. The method of manufacturing a display device, according to claim 6, wherein the scribe member is shifted to a predetermined start point by relative movement in association with movement of the insulating substrate.

10. A method of manufacturing a display device comprising:

a step of forming an effective display section, which forms the display device, on an insulating substrate; and

a step of forming a scribe line in a direction that intersects an edge of the insulating substrate,

wherein the effective display section has one side that agrees with the edge of the insulating substrate, and

the scribe line is spaced apart from the edge of the insulating substrate.
