Abstract
A reflective liquid crystal display (LCD) device includes a wall substantially extending between a peripheral portion of a first metal layer (pixel metal layer) formed in the peripheral region of the device with a light shield portion of a second metal layer formed in the pixel region of the device. The structure prevents light from reaching the substrate in the peripheral region of the device. Portions of the second metal layer formed in the peripheral region of the device may therefore be used for signal routing.
