Touch screen panel and display device

A touch screen panel, comprising:

• an array substrate, an assembling substrate arranged opposite to the array substrate, and a touch detection chip for detecting a touch, wherein
• the array substrate comprises:
• a first predetermined number of first self capacitive electrodes and first leads in one-to-one correspondence with the first self capacitive electrodes, the first leads are used for transmitting feedback signals generated by the first self capacitive electrodes to the touch detection chip;
• the assembling substrate comprises:
• a second predetermined number of second self capacitive electrodes and second leads in one-to-one correspondence with the second self capacitive electrodes, the second leads are used for transmitting feedback signals generated by the second self capacitive electrodes to the touch detection chip;
• and
• projections of the first self capacitive electrodes on the assembling substrate fall within a region on the assembling substrate without the second self capacitive electrodes.
