However, when the upper and lower planar substrates are pasted together, the support between the upper and lower substrates is already aligned. Therefore, after bending the display panel, it is easy to shift the position of the support between the upper and lower substrates, change the liquid crystal layer gap (Cell gap) of the panel, and reduce the quality of the display panel. Therefore, there is an urgent need for a method that can solve the aforementioned problems.

After the first substrate 100 and the second substrate 200 are bent, the second protruding structure 210A is in contact with the bump 112A. Therefore, the distance W1 between the bump 112A and the bump 114A is substantially equal to the amount of displacement of the second bump structure 210A relative to the bump 114A before and after the curved display panel 70A is bent. The first protrusion structure 110B includes a protrusion 112B and a protrusion 114B, and the protrusion 112B and the protrusion 114B (for example, between the bottom midpoints) are separated by a distance W2.

After the first substrate 100 and the second substrate 200 are bent, the second protruding structure 210C will be in contact with the bump 112C. Therefore, the distance W3 between the bump 112C and the bump 114C is substantially equal to the amount of displacement of the second bump structure 210C relative to the bump 114C before and after the curved display panel 70A is bent. The first protruding structure 110D that is about L2 / 2 from the first ridgeline X1 includes a bump 112D and a bump 114D, and a distance W4 is separated between the bump 112D and the bump 114D (for example, between the bottom midpoints).

Before the first substrate 100 and the second substrate 200 are bent, the second protruding structure 210E is in contact with the bump 114E. After the first substrate 100 and the second substrate 200 are bent, the second protruding structure 210E is in contact with the bump 112E. Therefore, the distance W5 between the bump 112E and the bump 114E is substantially equal to the amount of displacement of the second bump structure 210E relative to the bump 114E before and after the curved display panel 70A is bent. The first protrusion structure 110F includes a protrusion 112F and a protrusion 114F.

Before the first substrate 100 and the second substrate 200 are bent, the second protruding structure 210F is in contact with the bump 114F. After the first substrate 100 and the second substrate 200 are bent, the second protruding structure 210F is in contact with the bump 112F. Therefore, the distance W6 between the bump 112F and the bump 114F is substantially equal to the amount of displacement of the relative bump 114F of the second bump structure 210F before and after the curved display panel 70A is bent.

Instructions. For the description of the omitted parts, reference may be made to the foregoing embodiments, and the following embodiments are not repeated.

Please refer to FIGS. 11A and 11B at the same time. In this embodiment, the first substrate 100 has a first protruding structure 110A / 110B / 110C / 110D, and the second substrate 200 has a second protruding structure 210A / 210B. / 210C / 210D. The first raised structures 110A / 110B / 110C / 110D are arranged symmetrically to the first ridgeline X1. The second raised structures 210A / 210B / 210C / 210D are arranged symmetrically to the second ridgeline X2. In one embodiment, the first raised structures 110A / 110C are substantially symmetrical to the first raised structures 110B / 110D, and the second raised structures 210A / 210C are substantially symmetrical to the second raised structures 210B / 210D.

In this embodiment, each of the first raised structures 110A / 110B / 110C / 110D is a bump, and each of the second raised structures 210A / 210B / 210C / 210D is a gap. After the first substrate 100 and the second substrate 200 are bent, the first protruding structure 110A / 110B / 110C / 110D will move away from the second ridgeline X2 (horizontal) relative to the second protruding structure 210A / 210B / 210C / 210D (horizontal). Direction), the top part of the first protruding structure 110A / 110B / 110C / 110D away from the first ridgeline X1 110AT / 110BT / 110CT / 110DT does not correspond to the corresponding second protruding structure 210A / 210B / 210C / 210D Top surface 210AT / 210BT / 210CT / 210DT contacts.

In this embodiment, after the first substrate 100 and the second substrate 200 are bent, the top surface 110AT / 110BT / 110CT / 110DT of the first protruding structure 110A / 110B / 110C / 110D is opposite to the second protruding structure 210A / 210B. The displacement of the top surface of the spacer of / 210C / 210D 210AT / 210BT / 210CT / 210DT is the amount of dislocation of the first raised structure 110A / 110B / 110C / 110D. In one embodiment, the width of the top surface 210AT / 210BT / 210CT / 210DT of the spacer is greater than or equal to the corresponding misalignment amount.

In this embodiment, along the second arc surface S2 of the second substrate 200, the second convex structure 210A / 210B is located near the position about L2 / 2 from the second ridgeline X2. The top area of the spacer of the second raised structure 210A (or the spacer of the second raised structure 210B) is M1. The second raised structures 210C / 210D are located near the second ridgeline X2. The top area of the spacers of the second raised structures 210C (or the spacers of the second raised structures 210D) is M2, and M1> M2. In one embodiment, the top area of the spacers near the first ridgeline X2 or the sealant is smaller than the top area of the spacers of the second convex structure 210A (or the spacers of the second convex structure 210B).

Based on the above, by designing the first raised structures 110A / 110B / 110C / 110D and the second raised structures 210A / 210B / 210C / 210D of the display panel 90, the first curved surface S1 and the inside of the first substrate 100 are The distance d between the second curved surface S2 inside the second substrate 200 and the distance R between the third curved surface S3 outside the first substrate 100 and the fourth curved surface S4 outside the second substrate 200 can be maintained. Therefore, the difference between the liquid crystal layer gap before the panel is bent and the liquid crystal layer gap after the panel is bent is reduced.

Although the present invention has been disclosed as above with the examples, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field can make some modifications and retouching without departing from the spirit and scope of the present invention. The protection scope of the present invention shall be determined by the scope of the attached patent application.
