Display device having sealant and bezel area
A display device is disclosed. The display device includes a first substrate, a light emitting unit on the first substrate, a second substrate on the light emitting unit, and a seal member that attaches the first substrate to the second substrate. The light emitting unit includes a first electrode, a light emitting layer, and a second electrode. The seal member includes a straight portion and a curved portion. A radius of curvature of the curved portion lies substantially in a range between 0.2 mm and 2.5 mm.
1. A display device comprising:
a first substrate;
a light emitting unit on the first substrate, the light emitting unit including a plurality of unit pixels;
a second substrate opposite to the first substrate, the second substrate sealing the light emitting unit; and
a seal member that attaches the first substrate to the second substrate, the seal member including a straight portion and a curved portion, the seal member is positioned around the light emitting unit,
wherein a radius of curvature of the curved portion of the seal member lies substantially in a range between 0.2 mm and 2.5 mm,
wherein the seal member is a sealant,
wherein the unit pixels include a plurality of subpixels, the subpixels include a first electrode, a light emitting layer, and a second electrode, the unit pixels further include a thin film transistor having a semiconductor layer, a gate electrode, a source electrode, and a drain electrode,
wherein a ratio of a width of the straight portion to a width of the curved portion lies substantially in a range between 1:1 and 1:1.5; and
wherein the seal member is positioned on a bezel area, the bezel area is divided into an outside bezel area and an inside bezel area based on the seal member, and a width of the inside bezel area is greater than a width of the outside bezel area.
2. A display device comprising:
a first substrate;
a light emitting unit on the first substrate, the light emitting unit including a plurality of unit pixels, wherein the unit pixels include a plurality of subpixels, the subpixels include a first electrode, a light emitting layer, and a second electrode, and the unit pixels further include a thin film transistor having a semiconductor layer, a gate electrode, a source electrode, and a drain electrode;
a second substrate opposed to the first substrate;
a sealant that attaches the first substrate to the second substrate, the sealant including a straight portion and a curved portion, the sealant provided around the light emitting unit such that the light emitting unit is sealed in between the first substrate and the second substrate; and
a bezel area that includes an outside bezel area and an inside bezel area separated by the sealant provided on the bezel area, wherein a width of the inside bezel area is greater than a width of the outside bezel area,
wherein a radius of curvature of the curved portion of the sealant is between 0.2 mm and 2.5 mm, and
wherein a ratio of a width of the straight portion to a width of the curved portion is between 1:1 and 1:1.5.
