Please continue to refer to Figure 3A. In the functional display area A1, the area of the first sub-pixel P1 is AT, and the area of the color sub-pixel in the first sub-pixel P1 that is not blocked by the light shielding pattern LSP is AE (for example, the opening O1 area). The aperture ratio of the first sub-pixel P1 is defined as (AE*100%)/AT. In the functional display area A1, the aperture ratio of the first sub-pixel P1 (such as the first sub-pixel P11) that at least partially overlaps the first spacer SP1 is, for example, A%, and the opening ratio of the first sub-pixel P1 that does not overlap the first spacer SP1 The aperture ratio of the first sub-pixel P1 (such as the first sub-pixel P12) is, for example, B%, and the decreasing rate C% of the aperture ratio is defined as (B%-A%)/B%.

In the general display area A2, the area of the second sub-pixel P2 is AT’, and the area of the second sub-pixel P2 is AT’. The area of the color sub-pixel in the second sub-pixel P2 that is not blocked by the light-shielding pattern LSP is AE’ (for example, the area of the opening O3). The aperture ratio of the second sub-pixel P2 is defined as (AE’*100%)/AT’. In the general display area A2, the aperture ratio of the second sub-pixel P2 (such as the second sub-pixel P21) that at least partially overlaps the second spacer SP2 is, for example, A'%, and does not overlap the second spacer SP2. The aperture ratio of the second sub-pixel P2 (such as the second sub-pixel P22) is, for example, B'%, and the decrease rate of the aperture ratio C'% is defined as (B'%-A'%)/B'%.

For example, in one embodiment, in the functional display area A1, the aperture ratio of the first sub-pixel P1 (such as the first sub-pixel P11) that at least partially overlaps the first spacer SP1 is, for example, 17.3%. And the aperture ratio of the first sub-pixel P1 (such as the first sub-pixel P12) that does not overlap the first sub-pixel SP1 is, for example, 17.9%, and the decrease rate of the aperture ratio is 3.35%. In the general display area A2, with The aperture ratio of the second sub-pixel P2 (such as the second sub-pixel P21) that at least partially overlaps the second spacer SP2 is, for example, 48.7%, and the second sub-pixel P2 (such as the second sub-pixel P2) that does not overlap the second spacer SP2 (such as The aperture ratio of the second sub-pixel P22) is, for example, 54.7%, and the decrease rate of the aperture ratio is 11%.

In some embodiments, the problem of insufficient aperture ratio or dark spots in the display screen in the functional display area A1 can be improved through a design such that C%≦C’%. For example, the area of the first light-shielding portion LS1 provided corresponding to the first spacer SP1 in the functional display area A1 can be reduced so that the area of the first light-shielding portion LS1 is smaller than the area of the second light-shielding portion LS2 (see FIG. 3A ). But it is not limited to this. In other embodiments, the area of the first light-shielding portion LS1 , the first spacer SP1 and the position of the first light-shielding portion LS1 can be changed (to change the overlapping surface of the first light-shielding portion LS1 and the first sub-pixel P1 product), the shape of the first spacer SP1 and the first light-shielding portion LS1, the density of the first spacer SP1 in the functional display area A1, or a combination of at least the above two, etc., to achieve a design of C%≦C’%%.

Since the human eye is more sensitive to the light intensity variation of green light, in some embodiments, the first spacer SP1 may be at least partially connected to the first red sub-pixel R1 and/or the plurality of first sub-pixels P1 The first blue sub-pixels B1 are overlapped, so that the first light-shielding portion LS1 can be arranged corresponding to the first red sub-pixel R1 and/or the first blue sub-pixel B1 among the plurality of first sub-pixels P1. The influence (shielding) of the first light shielding part LS1 on the green light is reduced. In other words, the first light shielding portion LS1 overlaps with at least one of the first red sub-pixel R1 and the first blue sub-pixel B1 among the plurality of first sub-pixels P1. Similarly, the second spacer SP2 can be at least partially overlapped with the second red sub-pixel R2 and/or the second blue sub-pixel B2 among the plurality of second sub-pixels P2, so that the second light-shielding portion LS2 can be It is provided corresponding to the second red sub-pixel R2 and/or the second blue sub-pixel B2 among the plurality of second sub-pixels P2 to reduce the influence (shielding) of the second light shielding portion LS2 on the green light. In other words, the second light shielding portion LS2 overlaps with at least one of the second red sub-pixel R2 and the second blue sub-pixel B2 among the plurality of second sub-pixels P2.

4A to 4C illustrate changing the overlapping area of the first light shielding portion LS1 and the first sub-pixel P1 (such as the first sub-pixel P11) by changing the positions of the first spacer SP1 and the first light-shielding portion LS1. Example. The design of the general display area A2 can be referred to FIG. 2A to FIG. 2C and will not be repeated here. On the other hand, in the functional display area A1, the first spacer SP1 can be moved out of the color sub-pixel (such as the first red sub-pixel R1) in the first sub-pixel P1 to reduce the impact of the first light-shielding portion LS1. Color sub-pixel (such as the first red The shielding rate of the dice sub-pixel R1) increases the aperture rate of the first sub-pixel P1. In this way, as shown in FIGS. 2A and 4A , the overlapping area of the first light-shielding portion LS1 and the first sub-pixel P1 (such as the first sub-pixel P11 ) can be smaller than that of the second light-shielding portion LS2 and the second sub-pixel P2 (eg, the first sub-pixel P11 ). Such as the overlapping area of the second sub-pixel P21). In other embodiments, the first sub-pixel P1 overlapping the first light-shielding portion LS1 and the second sub-pixel P2 overlapping the second light-shielding portion LS2 include sub-pixels of the same color, but this disclosure does not take this as an example. limit. The shielding rate in this embodiment may be, for example, 100%-opening rate, but the disclosure is not limited thereto. For example, please refer to Figures 2D and 2E. Figure 2D illustrates signal lines, light shielding patterns LSP and active components AD. In Figure 2D, the area surrounded by two adjacent scan lines SL and two adjacent data lines DL (for example, the area surrounded by the center line of the signal line or the area surrounded by the edges on the same side of the signal line) can be defined. is a second sub-pixel P2, and continue to refer to Figure 2E. Figure 2E shows the second sub-pixel P2 defined in Figure 2D with a solid line. The overlap between the second sub-pixel P2 and the second light-shielding portion LS2 The area is shown at the bottom of the irregular dot network in Figure 2E.

Figures 5 and 6 illustrate two examples of changing the shape of the first spacer SP1. The design of the general display area A2 can be referred to FIG. 2A to FIG. 2C and will not be repeated here. On the other hand, in the functional display area A1, the shape of the first spacer SP1 can be changed into an ellipse (refer to FIG. 5), a rectangle (refer to FIG. 6), or other shapes with long sides extending in the second direction D2. Correspondingly, the shape of the first light shielding portion LS1 can be changed into an elliptical shape (see FIG. 5 ), a rectangular shape (see FIG. 6 ), or other shapes with long sides extending in the second direction D2. Under this design, the shape of the first light shielding portion LS1 may be different from the shape of the second light shielding portion LS2 (refer to FIG. 2A ).

In some embodiments, by changing the shape and/or size of the first light-shielding portion LS1, the first light-shielding portion LS1 can be hidden in the light-shielding portion LS3. That is to say, when viewing the light-shielding pattern LSP from a top view of the display panel, one can see corresponding multiple signal lines (multiple scan lines SL and multiple data lines DL as shown in Figure 3B), multiple corresponding signal lines in the functional display area A1. The first light-shielding portion LS1 is not visible through the light-shielding portion LS3 provided with an active element AD (refer to FIG. 3B) and a plurality of wires CL (refer to FIG. 3B).

In some embodiments, although not shown, the density of the first spacers SP1 in the functional display area A1 can be changed, for example, the density of the plurality of first spacers SP1 in the functional display area A1 is lower than that of the plurality of second gaps. The density of the sub-SP2 in the general display area A2 is used to reduce the number or shielding area of the first light-shielding portions LS1, thereby increasing the aperture ratio of the first sub-pixel P1 in the functional display area A1. Since the edge of the display panel is supported by the frame glue (not shown), the first spacer SP1 in the functional display area A1 disposed adjacent to the edge of the display panel has a smaller sliding ratio or range when subjected to external pressure, thereby reducing the installation cost. The first spacer SP1 in the functional display area A1. In other embodiments, a plurality of first spacers SP1 (eg, primary spacers) may be completely or partially replaced with secondary spacers.
