<p>A liquid crystal display is provided which reduces the substrate cost and shortens the wiring length to drive elements thereby decreasing wiring resistance and load on the drive power supply. A pixel array board is also provided, as well as a manufacturing process and a method for forming an image with the pixel array board. A silicon substrate 1 is used as an LCD pixel array. A through hole is formed in the silicon substrate 1 by means of anisotropic etching or the like. Formed in the through hole are an insulating layer 5 and a wiring conductor layer (for example, Cr-Cu-Au layer) 8 with a predetermined pattern. The wiring conductor layer 8 is bonded to a conductor layer (for example, Cr-Cu-Au layer) 8' of a drive element 10 through a solder layer 9, or by means of thermo-compression bonding between the Cr-Cu-Au layer 8 and the Cr-Cu-Au layer 8' to connect the LCD pixel array on the surface of silicon substrate 1 to the drive element 10 and the like on the bottom of silicon substrate 1.</p> |
