Abstract
A liquid crystal display includes a substrate, a thin film transistor, a first protection layer, a pixel electrode, a light blocking layer, a second protection layer, and a roof layer. The thin film transistor is disposed on the substrate. The first protection layer is disposed on the thin film transistor. The pixel electrode is disposed on the first protection layer. The light blocking layer is disposed on the pixel electrode to cover the thin film transistor. The second protection layer is disposed on the light blocking layer. The roof layer is disposed to face the pixel electrode, wherein a plurality of microcavities having injection holes are formed between the pixel electrode and the roof layer. The microcavities comprise liquid crystal molecules, and the first protection layer and the second protection layer have different etch rates.
