Liquid crystal display and method of manufacturing the same

A method manufacturing a liquid crystal display comprising:

• forming a thin film transistor on a substrate;
• forming a protection layer on the thin film transistor;
• forming a first electrode and a second electrode on the protection layer;
• forming a sacrificial layer on the second electrode;
• forming a roof layer on the sacrificial layer;
• removing the sacrificial layer to form a plurality of microcavities including a liquid crystal injection hole;
• injecting a photo-alignment material into the microcavities;
• irradiating polarized light to the photo-alignment material;
• baking the photo-alignment material;
• and
• injecting a liquid crystal material in the microcavities.
