Patent ID: 7973892

Claim:
A liquid crystal display device, comprising: a liquid crystal panel comprising a first substrate having a thin film transistor and forming a transmissive region and a reflective region thereon, a second substrate facing the first substrate and a liquid crystal layer interposed between the first and second substrates and being in an electrically controlled birefringence (ECB) mode; a first optical unit attached to an external surface of the first substrate and having a first polarizing layer; and a second optical unit attached to an external surface of the second substrate and having a second polarizing layer; and a single λ/2 compensation film interposed between the second substrate and the second polarizing layer, wherein a transmissive axis of the first polarizing layer and a director of the liquid crystal layer form an angle of 40 degrees to 50 degrees wherein at least one black matrix layer is formed between the second optical layer and the liquid crystal layer.
