Abstract
An exemplary liquid crystal module (2) includes a transparent substrate (222) having a color filter, a light guide plate (221) opposite to the transparent substrate, and a liquid crystal layer (223) sandwiched between the transparent substrate and the light guide plate. The light guide plate has a thin film transistor (TFT) array formed thereat. The liquid crystal module includes the light guide plate having the TFT array formed thereon, instead of conventionally including a separate TFT array substrate in addition to a light guide plate. This configuration of the light guide plate decreases an overall thickness and weight of the liquid crystal module compared with a conventional liquid crystal module. Moreover, the process of assembly of the liquid crystal module is simplified.
