Display device and manufacturing method thereof |
摘要 |
A display device is provided. A substrate includes a thin film transistor. A pixel electrode is connected to the thin film transistor. A common electrode is formed on the pixel electrode. A microcavity including liquid crystal molecules is interposed between the pixel electrode and the common electrode. A roof layer is formed on the common electrode. The roof layer includes at least one protrusion. A support member is formed under the at least one protrusion and in a column shape. The support member is surrounded by the liquid crystal molecules. An overcoat is formed on the roof layer and a side of the microcavity. |

1. A display device, comprising:
a substrate including a thin film transistor; a pixel electrode connected to the thin film transistor; a common electrode formed on the pixel electrode; a microcavity including liquid crystal molecules, wherein the microcavity is interposed between the pixel electrode and the common electrode, and wherein the microcavity includes an injection hole; a roof layer formed on the common electrode, wherein the roof layer includes at least one protrusion; a support member formed under the at least one protrusion and in a column shape, wherein the support member is surrounded by the liquid crystal molecules, wherein the support member is proximate to the injection hole such that a roof layer region proximate to the injection hole is prevented from being sagged down; and an overcoat formed on the roof layer and a side of the microcavity, wherein the overcoat covers the injection hole and the support member. |
