The invention discloses a display panel, a display apparatus and a display panel crosstalk adjusting method so as to solve a problem that crosstalk can be adjusted only via adjustment of parameters of the display panel through manual means according to technologies of the prior art, and the display panel cannot be adjusted in a highly efficient and accurate manner via too much manual operation. The display panel comprises a crosstalk adjusting module and at least one light-sensitive element positioned on a light receiving side of a first substrate; the light-sensitive element is used for determining a luminance value of the light-sensitive element and sending a determined luminance value to the crosstalk adjusting module, the crosstalk adjusting module is used for determining a crosstalk value corresponding to the light-sensitive element, and the crosstalk adjusting module is also used for adjusting shutdown voltage of an array substrate thin film transistor according to the crosstalk value corresponding to the light-sensitive element and preset crosstalk conditions. As adjustment of the shutdown voltage of the thin film transistor causes change in a leakage current in the thin film transistor and further leads to crosstalk change caused by the leakage current, no manual adjustment of the parameters of the display panel is needed for crosstalk adjustment.
