Abstract
In an exemplary display device of the present invention, a first microcavity filled with liquid crystal molecules is disposed on a substrate. A roof layer is disposed on an upper side and two facing first sides of the first microcavity. The two facing first sides are arranged in a first direction. A support member is disposed on one of two facing second sides of the first microcavity. The two facing second sides are arranged in a second direction crossing the first direction. An overcoat is disposed on the roof layer and the other of the two facing second sides of the first microcavity. The support member having a column shape is connected to the roof layer.
Claims20
A display device, comprising:
- a substrate;
- a first microcavity disposed on the substrate and, filled with liquid crystal molecules;
- a roof layer disposed on an upper side and two facing first sides of the first microcavity, wherein the two facing first sides are arranged in a first direction;
- a support member disposed on one of two facing second sides of the first microcavity, wherein the two facing second sides are arranged in a second direction crossing the first direction;
- and
- an overcoat disposed on the roof layer and the other of the two facing second sides of the first microcavity,
- wherein the support member having a column shape is connected to the roof layer.
A manufacturing method of a display device, comprising:
- forming a substrate including a pixel electrode and a thin film transistor, wherein the pixel electrode is electrically connected to the thin film transistor;
- forming a sacrificial layer on the pixel electrode;
- forming a lower insulating layer on the sacrificial layer;
- forming an organic material on the lower insulating layer to form a roof layer and a support member;
- removing the sacrificial layer to form a plurality of microcavities, wherein each of the plurality of microcavities is defined by the lower insulating layer, the pixel electrode and the support member;
- injecting a liquid crystal material into the plurality of microcavities;
- and
- forming an overcoat on the roof layer to seal the plurality of microcavities,
- wherein the support member includes a column shape, the roof layer is formed on the lower insulating layer, and the support member is connected to the roof layer.
