The present disclosure provides a display panel and a display apparatus. The display panel includes: a base substrate; pixel light-transmitting regions, each pixel light-transmitting regions includes: pixel light-transmitting region rows extending in a first direction and arranged in a second direction; at least one of the pixel light-transmitting region rows includes: a first pixel light-transmitting region, a second pixel light-transmitting region, and a third pixel light-transmitting region; a length of the third pixel light-transmitting region is less than that of the first pixel light-transmitting region in the second direction, and is less than that of the second pixel light-transmitting region in the second direction; and a first blocking structure on one side of the base substrate, an orthographic projection of the first blocking structure is in a gap between orthographic projections of two at least partially adjacent third pixel light-transmitting regions in the second direction on the base substrate.
