Abstract
A liquid crystal display apparatus is provided which requires a small, thin and compact area for mounting semiconductor chips for driving liquid crystal and, accordingly, has a reduced cost. Semiconductor chips for driving liquid crystal are mounted on a surface (for example, a first layer) of a multi-layer substrate. The surface has input lines to the chips and output lines from the chips. The input lines have lands for connecting adjacent multi-layer substrates to each other. At least one intermediate layer is formed between an upper layer and a lower layer, the intermediate layer having bus lines. The bus lines and the input lines of the first layer are connected to one another via through holes in the first layer. The output lines of the first layer and terminals of the third layer are connected to one another via through holes in the first, second and third layers.
