Embodiment Construction

[0045] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used in the drawings and description to refer to the same or like parts.

[0046] figure 1 It is a schematic top view of a display panel according to an embodiment of the present invention. Please refer to figure 1 , the display panel 100 has a first area 102 and a second area 104 next to the first area 102 . In the top view, the first area 102 has a frame pattern and surrounds the second area 104 . In addition, the display panel 100 includes a patterned light-shielding layer 110 located in the first region 102 . Specifically, the patterned light-shielding layer 110 in this embodiment has a frame-like pattern, and the first region 102 can be regarded as the region where the patterned light-shielding layer 110 is disposed. The edge of the patterned light-shiel...

Abstract

The invention discloses a display panel, which comprises an upper substrate, a display layer, a patterned light-shielding layer and a patterned oxide layer. The upper substrate has an outer surface. The display layer is covered by the upper substrate. The patterned light-shielding layer is disposed on the outer surface of the upper substrate and located in the first region. The patterned oxide layer is disposed on the outer surface of the upper substrate. The outer surface includes a first area and a second area beside the first area. Edges of the patterned light-shielding layer at least partially overlap the boundary between the first region and the second region. The patterned oxide layer is located in one of the first region and the second region, and exposes the other region of the first region and the second region.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to a display panel. Background technique [0002] In order to divide and define the display area, the display panel is usually configured with a patterned light-shielding layer such as a black matrix, wherein the patterned light-shielding layer can have a frame pattern or a matrix pattern, and is surrounded by a frame pattern or a matrix pattern. as the display area. The black matrix layer can not only define the display area, but also prevent unnecessary light leakage. [0003] For a liquid crystal display panel, a display layer including a liquid crystal material is disposed between an upper substrate and a lower substrate, and the upper substrate and the lower substrate are attached or assembled to each other via a sealant or an adhesive. When the frame glue or the adhesive is a light-curing material, the upper substrate needs to be a light-transmitting material, so that the ...
