Abstract
The present disclosure relates to a display device comprising a spacer and a manufacturing method thereof. The display device according to an embodiment of the present disclosure includes a thin film transistor disposed on a substrate, a bank disposed on the thin film transistor, and a spacer structure assembly including at least two spacers disposed on the bank. A first separation distance between a first separator and a second separator, among the spacers, at a first area of the display device is different from a second separation distance between the first separator and the second separator at a second area of the display device.
Claims25
A display device comprising:
- a thin film transistor disposed on a substrate;
- a bank disposed on the thin film transistor;
- and
- a spacer structure assembly including at least two spacers disposed on the bank,
- wherein a first separation distance between a first spacer and a second spacer, among the at least two spacers, at a first area of the display device is different from a second separation distance between the first spacer and the second spacer at a second area of the display device, and
- wherein each of the first and second spacers has an inverse tapered shape.
A manufacturing method of a display device including a spacer structure assembly, the method comprising:
- disposing a thin film transistor on a substrate;
- disposing a bank on the thin film transistor;
- disposing a photoresist on the bank;
- and
- performing photolithography on the photoresist by using a mask corresponding to a configuration of the spacer structure assembly, and thereby forming the spacer structure assembly including at least two spacers,
- wherein a first separation distance between a first spacer and a second spacer, among the at least two spacers, at a first area of the display device is different from a second separation distance between the first spacer and the second spacer at a second area of the display device.
