Abstract
A display device may include a substrate, a transistor, a pixel electrode, a roof layer, and a liquid crystal layer positioned in microcavities between the roof layer and the substrate. The roof layer may include a first roof portion and a second roof portion. The first roof portion may overlap the pixel electrode and may be directly connected to the second roof portion. The second roof portion may be positioned closer to the transistor than the first roof portion. A minimum distance between the substrate and the second roof portion may be less than a minimum distance between the substrate and the first roof portion.

A liquid crystal display, comprising:
- a substrate;
- a thin film transistor disposed on the substrate;
- a pixel electrode connected to the thin film transistor;
- a roof layer disposed on the pixel electrode;
- a liquid crystal layer positioned in a microcavity between the pixel electrode and the roof layer;
- and
- a light blocking member disposed between the pixel electrode and the thin film transistor,
- wherein the roof layer includes a flat portion and an inclined portion connected to the flat portion,
- wherein the inclined portion is inclined toward the substrate from the flat portion,
- wherein a lower surface of the inclined portion is disposed under an extension line of a lower surface of the flat portion, and
- wherein the inclined portion is disposed at a side of the microcavity.
A display device comprising:
- a substrate;
- a transistor;
- a pixel electrode;
- a roof layer comprising a first roof portion and a second roof portion, wherein the first roof portion overlaps the pixel electrode and is directly connected to the second roof portion, wherein the second roof portion is positioned closer to the transistor than the first roof portion, and wherein a minimum distance between the substrate and the second roof portion is less than a minimum distance between the substrate and the first roof portion;
- and
- a liquid crystal layer positioned in a microcavity between the substrate and the roof layer, the liquid crystal layer overlapping both the first roof portion and the second roof portion.
