OLED display device and method of manufacturing OLED display device
View Patent ↗An OLED display device includes a substrate, subpixel lines on the substrate and an applied-material separation layer on the substrate. Each of the subpixel lines includes subpixels of the same color disposed along a first axis. The applied-material separation layer has application separation openings. Each of the application separation openings includes subpixels of the same color that are consecutive in one subpixel line. Within each application separation opening, organic light-emitting films of the subpixels of the same color are connected by an organic light-emitting film made of the same material as material of the organic light-emitting films of the subpixels. Banks between application separation openings in each of the subpixel lines are different in position from banks between application separation openings in an adjacent subpixel line when seen along a second axis perpendicular to the first axis.
1. An OLED display device, comprising:
a substrate;
a plurality of subpixel lines on the substrate, each of the plurality of subpixel lines including a plurality of subpixels of the same color disposed along a first axis; and
an applied-material separation layer on the substrate, the applied-material separation layer having a plurality of application separation openings,
wherein each of the plurality of application separation openings includes a plurality of subpixels of the same color that are consecutive in one subpixel line,
wherein, within each application separation opening, organic light-emitting films of the plurality of subpixels of the same color are connected by an organic light-emitting film made of the same material as material of the organic light-emitting films of the subpixels, and
wherein banks between application separation openings in each of the plurality of subpixel lines are different in position from banks between application separation openings in an adjacent subpixel line when seen along a second axis perpendicular to the first axis,
wherein the plurality of subpixel lines are composed of red subpixel lines, blue subpixel lines, and green subpixel lines cyclically disposed along the second axis,
wherein each of subpixels in each subpixel line of the plurality of subpixel lines is different in position along the first axis with respect to each of subpixels in each of subpixel lines of the plurality of subpixel lines adjacent thereto, and
wherein banks between application separation openings in each of the plurality of subpixel lines are different in position from banks between application separation openings in an adjacent subpixel line of subpixels of the same color when seen along the second axis.
2. The OLED display device according to claim 1 , wherein a dimension along the second axis of a region connecting subpixels of each application separation opening is smaller than a dimension along the second axis of a region including a subpixel of each application separation opening.
3. The OLED display device according to claim 2 , wherein banks in one of two subpixel lines of subpixels of the same color adjacent to each other in the plurality of subpixel lines are different in position from banks in the other subpixel line by a distance between subpixels in the subpixel lines or more than a distance between subpixels in the subpixel lines when seen along the second axis.
4. The OLED display device according to claim 1 , wherein all subpixels included in each of the plurality of application separation openings are included in the same subpixel line.
5. The OLED display device according to claim 1 , wherein a number of included subpixels is the same among application separation openings including subpixels of the same color in the plurality of application separation openings.
6. The OLED display device according to claim 1 , wherein banks in one of two subpixel lines adjacent to each other in the plurality of subpixel lines are different in position from banks in the other subpixel line by a distance between subpixels in the subpixel lines or more than a distance between subpixels in the subpixel lines when seen along the second axis.
7. The OLED display device according to claim 1 , wherein each one of at least a part of the plurality of application separation openings includes subpixels of the same color in different subpixel lines.
8. The OLED display device according to claim 1 ,
wherein each of the plurality of subpixel lines is one of a red subpixel line, a blue subpixel line, and a green subpixel line, and
wherein each of application separation openings including subpixels of a specific color in the plurality of application separation openings includes subpixels of the specific color in different subpixel lines.
9. The OLED display device according to claim 8 , wherein, among the plurality of application separation openings, a number of included blue subpixels per application separation opening is smaller than a number of included green subpixels per application separation opening.
