ABSTRACT:
A liquid crystal display device includes a thin film transistor (TFT) array substrate10,a counter substrate22provided opposite to the TFT array substrate10and a liquid crystal layer28held between the TFT array and counter substrates10and22.The TFT array substrate10has display and frame areas31and32.There are pixel electrodes in the display area31which each have reflective and transparent portions33and34with convex and concave portions29and30,respectively. Convex and concave portions36and37are also provided in the frame area32which are substantially the same in shape as convex and concave portions29and30in the display area31.The surface of a photoresist coating film in the display area31shown by a dotted line39is substantially the same in configuration as that in the frame area32to make the column-like spacers27and38substantially the same in height. A cell gap between the TFT array and counter substrates10and22is made thereby substantially uniform.
