Abstract
A display panel and a display device, including a first substrate and a second substrate arranged opposite each other and spaced apart from each other, and a main spacer and a sub-spacer arranged between the first substrate and the second substrate, with bottom ends of both the main spacer and the sub-spacer arranged at the first substrate. In this display panel, by providing a part of a surface of the second substrate with a transparent conductive layer, the main spacer is able to directly press against the transparent conductive layer. By defining a groove in the second substrate with an opening thereof opposite the sub-spacer, a free end of the sub-spacer can be inserted into the groove when being applied with a supporting force. Thus, a step difference between the two spacers can increase by a thickness of the transparent conductive layer and a depth of the groove.
