Abstract:
1. An array substrate for a liquid crystal display device, comprising: a substrate including a first driving region, a second driving region, and a pixel region, the pixel region including a switching region and a storage region; a first n-type transistor in the first driving region, a second p-type transistor in the second driving region; a third transistor in the switching region, the third transistor including a gate electrode, an active layer, a source electrode, and a drain electrode; an extension portion in the storage region and extending from the active layer the extension portion excluding dopants; a metal pattern directly on and contacting the extension portion, wherein an end of the metal pattern is aligned with an end of the extension portion; a storage line over the metal pattern; and a pixel electrode in the pixel region and contacting the third transistor
