摘要： A display device includes a substrate, a semiconductor layer, an insulating layer, and a conductive layer. The semiconductor layer is disposed on the substrate, includes a channel of a first transistor, and includes a channel of a second transistor. The insulating layer is disposed on the semiconductor layer. The conductive layer is disposed on the insulating layer, includes a gate electrode of the first transistor, and includes a gate electrode of the second transistor. The channel of the first transistor includes a first first-element impurity ion and a second-element impurity ion different from the first first-element impurity ion. The channel of the second transistor includes a second first-element impurity ion identical to the first first-element impurity ion.

摘要： A liquid crystal display includes: a first substrate on which a display area and a non-display area disposed on an outside of the display area are defined; a first insulating layer, which is disposed in the non-display area on the first substrate; a barrier pattern, which is disposed on the first insulating layer; a seal pattern, which is disposed on the barrier pattern to overlap the barrier pattern; and a second substrate, which is disposed to face the first substrate.

摘要： A liquid crystal display panel includes substrates opposed to each other, a liquid crystal layer interposed between the substrates, a seal line surrounding an outer peripheral portion of the liquid crystal layer and disposed between the substrates and a liquid crystal alignment layer including a polyimide, the liquid crystal alignment layer including a first region and a second region disposed in an outer peripheral portion of the first region and disposed on one surface of at least one of the substrates, wherein at least a portion of the second region is overlapped with the seal line, the second region having a surface roughness value greater than that of the first region.

摘要： A method for manufacturing a display panel includes providing a mother substrate that includes a display area and a non-display area, and includes a first substrate, a second substrate facing the first substrate, and a sealant provided between the first substrate and the second substrate, generating a crack on the sealant through irradiation of laser onto the sealant between the first substrate and the second substrate, and cutting a part of the second substrate and a part of the sealant at a position corresponding to the crack.
