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

A method for increasing edge strength of a display panel, the display panel comprising a first substrate, a second substrate and a sealant, the sealant being disposed between the first substrate and the second substrate, the method comprising:

• providing the display panel;
• tilting the display panel so that the second substrate of the display panel and a horizontal plane form a tilt angle;
• grinding the second substrate to form a grinding end surface on the second substrate while the display panel is tilted at the tilt angle;
• and
• polishing the grinding end surface to form an end surface, wherein an arithmetic average roughness Ra of the end surface is between 0.001 and 0.04 μm, and a maximum roughness height Ry of the end surface is between approximately 0.1 and 0.5 μm.

A display panel, comprising:

• a first substrate comprising a first outer surface, a first inner surface and a first end surface, the first outer surface and the first end surface forming a first included angle therebetween;
• a second substrate disposed opposite to the first substrate and comprising a second outer surface, a second inner surface and a second end surface, the second outer surface and the second end surface forming a second included angle therebetween;
• and
• a sealant disposed between the first inner surface and the second inner surface, and comprising a sealant end surface between the first end surface and the second end surface;
• wherein an arithmetic average roughness Ra of the first end surface or the second end surface is between 0.001 and 0.04 μm, and a maximum roughness height Ry of the first end surface or the second end surface is between approximately 0.1 and 0.5 μm.

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.

A display panel, comprising:

• a first substrate comprising a first outer surface, a first inner surface and a first end surface, the first outer surface and the first end surface forming a first included angle therebetween;
• a second substrate disposed opposite to the first substrate, and comprising a second outer surface, a second inner surface and a second end surface, the second outer surface and the second end surface forming a second included angle therebetween;
• and
• a liquid crystal confined structure disposed between the first inner surface and the second inner surface, and the liquid crystal confined structure having a liquid crystal confined structure end surface disposed between the first end surface and the second end surface;
• wherein the first included angle is between 90 and 110 degrees, and the second included angle is between 70 and 110 degrees.
