#The present invention is described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown.

#In the drawings, the thickness of layers and regions are exaggerated for clarity. Like numerals refer to like elements throughout. It will be understood that when an element such as a layer, region or substrate is referred to as being “on” another element, it can be directly on the other element or intervening elements may also be present. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.

#A liquid crystal display according to an embodiment of the present invention now will be described in detail with reference to FIGS. 1, 2, 3 and 4.
