Abstract
An array substrate comprising an electrical connection block exposed to its surface. By manufacturing a passivation layer via hole in a passivation layer, a drain electrode or a pixel electrode of a thin-film transistor is exposed, so that the electrical connection block fills the passivation layer via hole and is provided in contact with the drain electrode or the pixel electrode. Thereby, when the electrical characteristic value of a TFT is measured, the pixel probe of a measuring apparatus may be electrically connected with the drain electrode or the pixel electrode by directly contacting the electrical connection block, so that the measuring of the electrical characteristics of the TFT may be realized.
