A display substrate and a method thereof, a display panel and a display device are provided. The display substrate includes: a base substrate; and at least one first signal line and a first insulating layer which are disposed on the base substrate; a surface of the first insulating layer away from the base substrate and a surface of the at least one first signal line away from the base substrate are parallel with the base substrate and are substantially located in a continuous flat plane. The first insulating layer which is disposed side by side with the first signal line can improve the surface flatness level of the display substrate and prevent the subsequently formed structures on the display substrate suffering from display defectives due to a too large step.

Display substrate and manufacturing method thereof, display panel and display device

A photomask and an exposure method are provided. The photomask includes a photomask body including a first surface and a second surface opposite to each other; and a first light-transmissive region penetrating through the first surface and the second surface, wherein a light adjustment component is in the first light-transmissive region and configured to converge a first light beam incident onto the first surface to a second light beam emergent from the second surface, and a cross-sectional area of the first light beam sectioned by the first surface is larger than that of the second light beam sectioned by the second surface.

Photomask and exposure method

An array substrate, a method for manufacturing the same, a liquid crystal display panel, and a display device are provided. The array substrate includes a first substrate, signal lines and an insulating layer; the insulating layer is disposed on the first substrate, and grooves are disposed on a side of the insulating layer facing away from the first substrate and disposed in a region of the insulating layer corresponding to a non-display region of the array substrate; and the signal lines are disposed on inner walls of the grooves, a direction of the inner walls of the grooves is arranged such that at least a portion of light incident on the signal lines from a side of the first substrate facing away from the signal lines is reflected to a display region of the array substrate.
