Abstract:
1. A TFT surface display device, comprising: a plurality of display element units that are arranged on a display substrate and that include a plurality of unit circuits, and a plurality of pixel circuits, each unit circuit provided in association with each display element unit, each unit circuit having i) a single input node to receive a scanning signal, and ii) a single output node to output said scanning signal, each one pixel circuit connected directly to said output node of each unit circuit in one-to-one correspondence, a plurality of stages of said unit circuits being cascade connected to transfer said scanning signal from a preceding stage to a succeeding stage, each unit circuit including a transistor that is connected from said input node directly to said output node of said each unit circuit and that receives said scanning signal supplied to said input node of said each unit circuit from a previous stage, said transistor, when turned on, outputting said scanning signal received at said input node to said output node of said each unit circuit for supply to said pixel circuit and a next stage thereby transfer said scanning signal from the preceding stage to the succeeding stage, said transistors included in even and odd stages of said unit circuits having gate terminals thereof connected in common directly to a single phase clock signal, said transistors included in odd stages of said unit circuits being controlled to be turned on and off respectively by a first logic level and a second logic level of said single phase clock signal supplied in common directly to said gate terminals of said transistors, while said transistors included in even stages of said unit circuits being controlled to be turned off and on respectively by said first logic level and said second logic level of said single phase clock signal supplied in common directly to said gate terminals of said transistors, wherein said TFT surface display device has a nonrectangular outer shape providing a non-rectangular display region, said display element units arranged in a nonrectangular area corresponding to said non-rectangular outer shape, and wherein said transistor in said unit circuit and said pixel circuit connected to said output node of said unit circuit are arranged in one-to-one correspondence within said display element unit as a set to constitute one of said display element units, and a plurality of said sets of said transistors and said pixel circuits are arrayed together to form substantially an entire area of a display area.
