Abstract: A display panel is disclosed, which comprises: a first substrate; a second substrate opposite to the first substrate and comprising a display region and a border region; a sealant disposed between the first substrate and the second substrate and surrounding the display region; and plural protrusions disposed on the border region and respectively has a top surface facing to the first substrate, wherein the sealant has a central dummy line along a longitude direction thereof, and the plurality of protrusions disposed on a region which is defined by peripheries extending from the central dummy line toward two opposite direction substantially vertical to the central dummy line within a distance ranging from 0 ?m to 200 ?m, wherein on a unit area of the region, a sum of areas of the top surfaces of the plurality of protrusions is 1% to 5% of the unit area.

Abstract: The present invention relates to a drill bit structure which comprises a body. The body has a free end, an intermediate section and a connection end. The body comprises a first groove portion, a second groove portion, a third groove portion, a fourth groove portion and a fifth groove portion. The first groove portion is partially overlapped with the third groove portion from the free end. The second groove portion is partially overlapped with the fourth groove portion from the free end. After extending a preset axial distance from the free end, the first groove portion and the second groove portion are partially overlapped with each other by forming an intersecting protrusion. The fifth groove portion is extended from the intermediate section toward the connection end. The first, second, third and fourth groove portions are extended to the fifth groove portion.
