Abstract
A circuit board structure, a binding test method and a display device are provided. The circuit board structure includes a first circuit board including a first binding region, a second circuit board including a second binding region matching with the first binding region, and a test circuit configured to test an alignment state of the first circuit board and the second circuit board. The test circuit includes multiple first electrodes and multiple second electrodes insulated from each other and arranged on the first circuit board, and multiple third electrodes arranged on the second circuit board. A group including one of the first electrodes and one of the second electrodes matches with one of the third electrodes, so that a current flows through the test circuit in case that the test circuit is supplied with power.
