Abstract
A method of fabricating a liquid crystal display (LCD) is performed on a glass substrate. First, an organic layer is formed on the glass substrate and then a pattern layer is formed on the organic layer. Next, by employing an attenuated mask, the pattern layer is formed as a plurality of first protrusions that are unconnected with each other and each of the first protrusions has a ladder profile. Next, a dry etching process is performed to remove all of the first protrusions and part of the organic layer so as to form the remaining organic layer as a plurality of second protrusions corresponding to the first protrusions. The second protrusion has two sloped and intersected sidewalls.
