The invention relates to a display panel, a display device and a preparation method of the display panel. The display panel comprises a substrate; the display layer is located on one side of the substrate, and the display layer comprises a plurality of sub-pixels; the touch layer is located on the side, away from the substrate, of the display layer, and the touch layer comprises a latticed touch electrode; the visual angle adjusting grating is in contact with the face, away from the display layer, of the latticed touch electrode; and the vertical projection of the visual angle adjusting grating on the substrate is overlapped with the vertical projection of at least part of the latticed touch electrode on the substrate. According to the technical scheme, on the basis that the display panel is peep-proof, the preparation process of the display panel is simplified, and the production cost is reduced.

The utility model discloses an external grid bar mounting structure and glass door and window belong to door and window technical field. External grid bar mounting structure includes glass, first grid bar and second grid bar. First grid bar and second grid bar are respectively established in the opposite sides of glass, and the side of first grid bar towards glass is equipped with first storage wall and first shield wall, and the side of second grid bar towards glass is equipped with second storage wall and second shield wall, and the side of first storage wall away from first shield wall is equipped with the connecting glue who links with glass, and the side of second storage wall away from second shield wall is equipped with the connecting glue who links with glass, and first shield wall and second shield wall are used for reducing the visible angle of connecting glue exposed through glass respectively. The utility model discloses set up storage structure and shield structure on the grid bar, effectively block and shield connecting glue, not only solve the glue leakage problem of the grid bar in the prior art, but also improve the beauty and connection firmness of the grid bar.

The utility model discloses a color film substrate, a display panel and a vehicle, the color film substrate comprises a color film support layer, the color film support layer comprises a color film bottom plate and a black matrix layer, the black matrix layer is arranged on the surface of one side of the color film bottom plate in the thickness direction, a plurality of mounting grooves arranged in a matrix are formed in the color film support layer, and the mounting grooves are arranged in the color film bottom plate. In the thickness direction of the color film supporting layer, the mounting groove penetrates through the black matrix layer and at least part of the color film bottom plate; and the plurality of mounting grooves are filled with the color films. According to the color film substrate provided by the utility model, on one hand, in the process that light rays penetrate through the color film substrate, when the light rays penetrate through the color films in the more than two mounting grooves, the included angle between the light rays and the thickness direction of the color film substrate is reduced, and the light rays penetrating through the color films in the more than two mounting grooves are distorted; on the other hand, a grating matrix can be formed on the color film bottom plate, so that the visual angle of the display panel can be reduced, the peep-proof effect is achieved, a peep-proof layer does not need to be arranged, and the production cost can be reduced.
