Please refer to Figure 1 to Figure 3. Figure 1 shows the schematic appearance of the flexible display panel of the present invention in the folded state, Figure 2 shows the schematic appearance of the flexible display panel of the present invention in the unfolded state, and Figure 3 shows the appearance of the flexible display panel of the present invention A schematic top view of the flexible display panel. As shown in FIGS. 1 to 3 , the flexible display panel 1 of the present invention includes a substrate 10 , a first pixel array 20 and a second pixel array 30 . The substrate 10 includes a first non-flexible portion 12 and at least one flexible portion 14 . The flexible part 14 is connected to at least one side of the first non-flexible part 12, and the first non-flexible part 12 and the flexible part 14 are preferably integrally formed, that is, the first non-flexible part 12 and the flexible Both the folded parts 14 are different parts of the same structure made of the same material, rather than being formed by splicing or bonding different structures. The first non-foldable part 12 has a non-flexible characteristic, that is, it is a fixed planar structure in the folded state or the unfolded state (unfolded state), while the flexible part 14 has a bendable characteristic, and it is in the unfolded state. The bottom is a planar structure, while in the folded state it is a curved structure. The material of the substrate 10 can be any flexible material such as plastic, but not limited thereto. In the unfolded state, the first non-flexible portion 12 and the flexible portion 14 can substantially form a planar structure, that is, the first non-flexible portion 12 and the flexible portion 14 can be substantially coplanar, and when folded In this state, the flexible part 14 can be bent along the second direction D2 according to the first direction D1 as the axis, wherein the first direction D1 and the second direction D2 can be substantially orthogonal to each other, and the folding angle of the flexible part 14 Or the curvature can be adjusted depending on the application. As shown in FIG. 3 , the first pixel array 20 is disposed on the first non-flexible portion 12 of the substrate 10, wherein the first pixel array 20 includes a plurality of first-time pixels 20P, and the first-time pixel 20P may include a plurality of the following The array is arranged to display sub-pixels of different colors such as red sub-pixels, green sub-pixels and blue sub-pixels. In addition, the second pixel array 30 is disposed on the flexible part 14 of the substrate 10, wherein the second pixel array 30 includes a plurality of second sub-pixels 30P, and the second sub-pixels 30P may include a plurality of arrays arranged for displaying The sub-pixels of different colors are, for example, red sub-pixels, green sub-pixels and blue sub-pixels. The first pixel array 20 and the second pixel array 30 of the present invention respectively select an electroluminescent display array, such as an organic light emitting diode display array, that is to say, each first pixel 20P and each second pixel 30P can respectively include At least one organic light emitting diode element and other necessary elements for providing display functions such as thin film transistor elements, storage capacitor elements and the like. In addition, the first pixel array 20 and the second pixel array 30 can be driven by a driving circuit (not shown). The first pixel array 20 and the second pixel array 30 of the present invention are not limited to electroluminescent display arrays, but may also be other types of self-luminous display arrays or non-self-luminous display arrays.

The first sub-pixels 20P have a first configuration density in the first direction D1, the second sub-pixels 30P have a second configuration density in the first direction D1, and the second configuration density of the second sub-pixels 30P is smaller than that of the first sub-pixels The first configuration density of 20P. In the first direction D1, the first non-flexible portion 12 and the flexible portion 14 may have substantially the same width in the first direction D1, and in this case, the number of the second sub-pixels 30P is less than that of the first The number of sub-pixels 20P. For example, each first sub-pixel 20P has a first size, each second sub-pixel 30P has a second size, and the second size is larger than the first size. To be precise, each sub-pixel 20P has a first width W1 in the first direction D1, and each second sub-pixel 30P has a second width W2 in the first direction D1, wherein the second width W2 is larger than the first width W2. The width W1, and the distance between two adjacent second sub-pixels 30P in the first direction D1 may be selectively greater than the distance between two adjacent first-time pixels 20P in the first direction D1. In addition, each first sub-pixel 20P has a first length L1 in the second direction D2, each second sub-pixel 30P has a second length L2 in the second direction D2, and the first length L1 may be substantially equal to, greater than or less than the second length L2.

Under the above-mentioned configuration, the second sub-pixel 30P of the flexible part 14 has greater structural strength, and there is a larger buffer space between adjacent second sub-pixels 30P, so the force received when being bent Therefore, the structure on the flexible part 14 is less likely to be peeled off due to repeated bending, so the reliability of the flexible display panel 1 of the present invention for bending and bending can be effectively increased. In addition, the first non-flexible part 12 and the flexible part 14 of the flexible display panel 1 of the present invention are integrally formed, which can also improve the reliability of bending and bending.

A non-flexible part 12 is electrically connected to a part of the first sub-pixel 20P and a part of the second sub-pixel 30P on the flexible part 14 . The first signal line 42 and the second signal line 44 in the first non-flexible part 12 have a first line distance G1 in the first direction D1, and the first signal line 42 and the second signal line in the flexible part 14 The lines 44 have a second line distance G2 in the first direction D1, and the second line distance G2 is greater than the first line distance G1.
