Liquid crystal display and manufacturing method thereof |
摘要 |
A manufacturing method of a liquid crystal display includes: providing a pixel electrode on an insulation substrate; providing a sacrificial layer on the pixel electrode; providing a common electrode on the sacrificial layer; providing a photoresist layer on the common electrode; exposing a portion of the photoresist layer, common electrode and the sacrificial layer with light; developing the portion of the photoresist layer exposed with the light; etching a layer between the photoresist layer and the sacrificial layer using the developed photoresist layer as a mask to expose the portion of the sacrificial layer exposed with the light; removing the portion of the sacrificial layer exposed with the light; providing a roof layer on the insulation substrate and etching the roof layer to form a liquid crystal injection hole therein; and removing the sacrificial layer exposed through the liquid crystal injection hole to form a microcavity. |

1. A method of manufacturing a liquid crystal display, the method comprising:
providing a pixel electrode on an insulation substrate; providing a sacrificial layer on the pixel electrode; providing a common electrode on the sacrificial layer; providing a photoresist layer on the common electrode; exposing a portion of the photoresist layer, common electrode and the sacrificial layer with light; developing the portion of the photoresist layer exposed with the light; etching a layer between the photoresist layer and the sacrificial layer using the developed photoresist layer as a mask to expose the portion of the sacrificial layer exposed with the light; removing the portion of the sacrificial layer exposed with the light; providing a roof layer on the insulation substrate and etching the roof layer to form a liquid crystal injection hole therein which exposes the sacrificial layer; and removing the sacrificial layer exposed through the liquid crystal injection hole to form a microcavity. |
