Disclosed in embodiments of the present disclosure are a display panel, a preparation method thereof and a display apparatus. The display panel includes: a first blocking dam located in the blocking area and surrounding the hole area, a second blocking dam located on one side of the first blocking dam close to the hole area and surrounding the hole area, a heightening layer located between the first blocking dam and the second blocking dam, a crack detect wire located on one side of the second blocking dam close to the hole area, at least two connection leading wires leading the crack detect wire out to the display area through the blocking area; in a direction perpendicular to a plane where the display panel is located, an orthographic projection of an area between the connection leading wires has an overlap area with an orthographic projection of the heightening layer.

Display panel and preparation method thereof and display apparatus

The present invention provides a class of molecular glass photoresist (I and II) comprising bisphenol A as a main structure and their preparation. The molecular glass photoresist is formulated with a photoacid generator, a cross-linking agent, a photoresist solvent, and other additives into a positive or negative photoresist. A photoresist with a uniform thickness is formed on a silicon wafer by spin-coating. The photoresist formulation can be used in modern lithography, such as 248 nm photolithography, 193 nm photolithography, extreme-ultraviolet (EUV) lithography, nanoimprint lithography, electron beam lithography, and particularly in the EUV-lithography technique.
