Problems solved by technology

[0005] If the non-black photoresist layer cannot reach a certain thickness, the color of the frame area will be darker, especially the white frame will turn blue, which will affect the appearance
And if the thickness of the non-black photoresist layer is enough to block the color transmission of the black photoresist layer, the thickness of the masking layer will be too large

Embodiment 1

[0045] An embodiment of the present invention provides a display panel, see figure 1 , the display panel includes a transparent substrate 1, the transparent substrate 1 is divided into a frame area 1a and a display area 1b, and the frame area 1a is arranged around the display area 1b.

[0046] combine figure 2 , figure 2 for figure 1 A schematic cross-sectional view of the display panel shown, as figure 2 As shown, the display panel also includes a non-black photoresist layer 2 and a black photoresist layer 3, the non-black photoresist layer 2 and the black photoresist layer 3 are sequentially arranged on the frame area 1a of the transparent substrate 1, and the black photoresist layer 2 and the non-black photoresist layer 3 are provided with a diffuse reflection structure 5 .

[0047] Figure 3a and Figure 3b The shielding layer of the display panel in the embodiment of the present invention and the shielding layer of the existing display panel reflect the light inc...

Embodiment 2

[0057] An embodiment of the present invention provides a display panel. In this embodiment, the display panel is an OGS (One Glass Solution, integrated touch) panel. see Figure 4 , the display panel includes a transparent substrate 1, the transparent substrate 1 is divided into a frame area 1a and a display area 1b, and the frame area 1a is arranged around the display area 1b.

[0058] combine Figure 5 , Figure 5 for Figure 4 The schematic cross-sectional view of the display panel along the X direction, such as Figure 5 As shown, the display panel also includes a non-black photoresist layer 2, a black photoresist layer 3 and an electrode layer 4. The non-black photoresist layer 2 and the black photoresist layer 3 are sequentially arranged on the frame area 1a of the transparent substrate 1, and the black photoresist layer The junction surface of the photoresist layer 2 and the non-black photoresist layer 3 is provided with a diffuse reflection structure 5 . The elect...

Embodiment 3

[0074] The structure of the display panel provided in this embodiment is basically the same as the structure of the display panel in Embodiment 2, the difference is that, as Image 6 As shown, the display panel of this embodiment may further include an FPC (Flexible Printed Circuit board, flexible printed circuit board) 7 with a touch IC (Integrated Circuit, integrated circuit) chip, and the FPC 7 is electrically connected to the electrode layer 4 .

[0075] It should be noted that, for simplicity, Image 6 The specific structure of the electrode layer 4 is not shown in the figure.

[0076] Since the structure of the display panel in this embodiment is basically the same as the structure of the display panel in the second embodiment, it has the same effect as the display panel provided in the second embodiment.

[0077] In addition, the display panel of this embodiment may further include a protective layer 6 formed on the electrode layer 4 . The protection layer 6 can be an...

Abstract

The embodiment of the invention discloses a display panel and a manufacturing method thereof as well as a display device, and belongs to the technical field of semiconductors. The display panel comprises a transparent substrate, a non-black photoresist layer, and a black photoresist layer, wherein the transparent substrate is divided into a border area and a display area; the border area is arranged around the display area; the non-black photoresist layer and the black photoresist layer are sequentially arranged on the border area of the transparent substrate; a scattered reflecting structure is arranged on a junction surface of the black photoresist layer and the non-black photoresist layer. The scattered reflecting structure is arranged on the junction surface of the black photoresist layer and the non-black photoresist layer, so that the reflectivity of the black photoresist layer can be reduced, the color of the black photoresist layer seen by eyes becomes lighter, and further the thickness of the non-black photoresist layer can be reduced.

Description

technical field [0001] The present invention relates to the technical field of semiconductors, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Flat panel displays can be seen everywhere in people's lives, and one of the important components is the display panel. Existing display panels usually include a transparent substrate and a shielding layer. The transparent substrate is divided into a display area and a frame area. The frame area is arranged around the display area. The shielding layer is arranged in the frame area of ​​the transparent substrate. The shielding layer is mainly used to shield signal lines. And play a decorative role. [0003] In order to obtain different product appearances, the border area needs to appear black or non-black. If the masking layer is formed on a transparent substrate using a black photoresist, the border will be black. And if the shielding layer is set to include a b...
