  • Publication number: 20210157195
    Abstract: The invention discloses a display panel having a display region and a wire out region on one side of the display region, comprising: a first substrate including a main body part and a glue blocking part connected to the main body part, a thickness of the main body part being different from a thickness of the glue blocking part; a second substrate opposite to the first substrate; and a sealant arranged between the first substrate and the second substrate, and located between the display region and the wire out region, wherein the glue blocking part is located on one side of the sealant close to the wire out region. The thickness of the main body part of the first substrate in the display panel of the invention is different from the thickness of the glue blocking part, and before curing, the sealant does not spill into the wire out region due to obstruction action of the glue blocking part, thereby not affecting a peeling process of the panel after cutting.
