Claim:
1. A liquid crystal display comprising: a thin film transistor disposed on a substrate; a passivation layer disposed on the thin film transistor; a pixel electrode disposed on the passivation layer and at a light transmitting area; an opposing electrode disposed on the pixel electrode and spaced apart from the pixel electrode; a liquid crystal layer disposed in a plurality of microcavities between the pixel electrode and the opposing electrode; a roof layer overlapping the pixel electrode, wherein an injection hole of at least one of the microcavities is exposed through a valley and the roof layer and the opposing electrode do not overlap the valley; a buffer zone disposed between the light transmitting area and the valley; a light blocking member overlapping the valley; and a first insulating layer disposed between the passivation layer and the pixel electrode, wherein the opposing electrode is disposed between the microcavity and the roof layer, wherein a height of the microcavity in the buffer zone is higher than a height of the microcavity in the light transmitting area, wherein the first insulating layer is formed through a different step than the passivation layer, and wherein the first insulating layer includes a first opening where the first insulating layer is not overlapping the buffer zone and the valley.
