摘要： A liquid crystal display device includes a thin film transistor (TFT) array substrate 10, a counter substrate 22 provided opposite to the TFT array substrate 10 and a liquid crystal layer 28 held between the TFT array and counter substrates 10 and 22. The TFT array substrate 10 has display and frame areas 31 and 32. There are pixel electrodes in the display area 31 which each have reflective and transparent portions 33 and 34 with convex and concave portions 29 and 30, respectively. Convex and concave portions 36 and 37 are also provided in the frame area 32 which are substantially the same in shape as convex and concave portions 29 and 30 in the display area 31. The surface of a photoresist coating film in the display area 31 shown by a dotted line 39 is substantially the same in configuration as that in the frame area 32 to make the column-like spacers 27 and 38 substantially the same in height. A cell gap between the TFT array and counter substrates 10 and 22 is made thereby substantially uniform.
