Display panel and method for narrowing edges and increasing edge strength thereof

A display panel, comprising:

• a first substrate;
• a second substrate disposed opposite to the first substrate;
• a liquid crystal layer disposed between the first substrate and the second substrate;
• a first photo spacer disposed on the first substrate and between the first substrate and the second substrate;
• a second photo spacer disposed on the first substrate and between the first substrate and the second substrate, and the second photo spacer and the first photo spacer forming a trench therebetween;
• and
• a sealant disposed between the first substrate and the second substrate and within the trench;
• wherein the first photo spacer is placed outside the sealant and far from the liquid crystal layer, the second photo spacer is placed inside the sealant and next to the liquid crystal layer, the first photo spacer and the first substrate and the second substrate at a corresponding position form an end surface going from the first substrate, the first photo spacer and the second substrate, and the end surfaces of the first substrate, the first photo spacer and the second substrate are coplanar.
