A liquid crystal display apparatus has a transparent substrate having a transparent common electrode formed thereon; an active matrix substrate having pixels with reflective pixel electrodes, the pixels being formed in column and row directions on the matrix substrate in a matrix fashion, each pixel having a switching transistor with a gate, a drain and a source, and a signal-charging capacitor; a liquid crystal layer provided between the common electrode and the pixel electrode; a column-signal electrode driver and a row-scanning electrode driver for activating the matrix substrate; column-signal electrodes connected to the column-signal electrode driver, the gate being connected to each column-signal electrode; and row-scanning electrodes connected to the row-scanning electrode driver, the drain being connected to each row-scanning electrode, each pixel electrode being provided at an intersection of each column-signal electrode and each row-scanning electrode, each pixel electrode and the capacitor being connected to the source. The matrix substrate has a first, a second, a third, and a fourth metal layer formed in order, via interlayer insulating layers between adjacent layers, on a wiring layer having the gate formed therein. The column-signal and row-scanning electrodes are formed in the first and second metal layers, respectively. Or, the column-signal electrodes and the row-scanning electrodes are formed in the second and the first layer, respectively. Wirings for carrying signals to be displayed are connected to the column-signal electrode driver, each wiring having a first wiring portion and a second wiring portion formed in the second and third metal layers, respectively, the first and second portions being electrically connected to each other through a via hole between the second and third metal layers.
