Device substrate and liquid crystal panel
First Claim
1. A device substrate having elements and a control circuit thereof formed monolithically;
- comprising;
a base substrate;
an element array including elements arranged in a matrix on the base substrate; and
a control circuit being placed along a side of the element array on the base substrate for controlling the elements by a row or by a column,the control circuit having a configuration of arranging unit control circuits corresponding to control units of the elements consecutively in a one-dimensional manner, andan arrangement pitch of the unit control circuits being smaller than that of the control units of the elements, and a difference between both of the pitches being equal to or smaller than a minimum wiring width or a minimum wiring pitch allowable in the control circuit.

Abstract
A frame size of a device substrate is reduced without a considerable change of a layout. An element side substrate 10 of a liquid crystal panel includes an element array having display elements 41, and a row control circuit 12 controlling the display elements 41 by a row, formed on a base substrate 11 monolithically. The row control circuit 12 has a configuration of arranging flip-flop circuits 13 corresponding to rows of the display elements 41 consecutively in a one-dimensional manner. An arrangement pitch P_G of the flop-flop circuits 13 is smaller than that P_G_PIX of the rows of the display elements 41, and also a difference between both of the pitches is set to be equal to or smaller than a minimum wiring width or a minimum wiring pitch allowable in the row control circuit 12. A video signal line group, a level shifter, or the like is placed in a vacant area which is obtained by a reduction of the row control circuit 12 in the longitudinal direction thereof. A column control circuit may be reduced in the longitudinal direction thereof with a similar method.
