Patent ID: 7515230

Claim:
An array substrate comprising: a transparent substrate including a reflective window that reflects an ambient light and a transmissive window that transmits an artificial light; an organic insulation layer disposed over the transparent substrate, the organic insulation layer being thinner gradually at a boundary between the transmissive window and the reflective window; a pixel electrode formed in the transmissive region; a reflective layer disposed over the organic insulation layer of the reflective window; a light blocking pattern disposed at the boundary between the transmissive window and the reflective window to prevent a light leakage, a switching part that is electrically connected to a gate line, a source line and the pixel electrode to apply an image signal to the pixel electrode, an alignment film rubbed along a rubbing direction; a first boundary between the reflective window and the transmissive window disposed in that sequence along the rubbing direction; a second boundary between the transmissive window and the reflective window disposed in that sequence along the rubbing direction; wherein the light blocking pattern is spaced apart from the gate line and disposed at only the first boundary to prevent a light leakage, the light blocking pattern is longer than a side portion of the transmissive window, and the light blocking pattern overlaps with the side portion of the transmissive window by a first length, and the second boundary is inclined steeper than the first boundary.
