Display panel, method of manufacturing the same and display device
View Patent ↗The invention discloses a display panel, a method of manufacturing the same and a display device so as to simplify a process of transmitting an electrical signal between a first substrate and a second substrate of the display panel at a lower cost. The display panel includes a first substrate and a second substrate disposed opposite to each other. The first substrate has a concave groove surrounded by a convex section and facing the second substrate. The display panel also includes an electrode layer on the surface of the groove and having at least one first conductive section extending outward from inside of the concave groove to the top end face of the convex section; and at least one second conductive section on the second substrate and electrically connected with the respective first conductive section.

an electrode layer disposed on an inside surface of the concave groove and including at least one first conductive section extending outward from inside of the concave groove to a top end surface of the convex section; and
at least one second conductive section disposed on the second substrate and electrically connected with the first conductive section at the top end surface of the convex section.
2. The display panel according to claim 1 , further comprising a preset spacing between a projection of the convex section onto the first substrate or the second substrate in a vertical direction and an edge of the first substrate or the second substrate.
3. The display panel according to claim 2 , further comprising a frame seal located in a region of the vertical projection of the concave groove onto the first substrate or the second substrate or located in the preset spacing.
4. The display panel according to claim 1 , wherein a pattern of the projection of the convex section onto the first substrate or the second substrate in the vertical direction is the same as a pattern of an edge frame of the display panel and the convex section is a continuous and integral structure; or the pattern of the projection of the convex section onto the first substrate or the second substrate in the vertical direction is the same as the pattern of an edge frame of the display panel, and the convex section includes a plurality of discrete convex sub-sections.
5. The display panel according to claim 4 , wherein the pattern of the projection of the convex section onto the first substrate or the second substrate in the vertical direction is rectangular, and the first conductive section is distributed on the top end face of at least one edge frame of the convex section.
