Abstract
The invention proposes an electro-optical matrix display device (10) including at least one bottom substrate plate (12) of overall rectangular shape carrying an electro-optical layer, a series of transverse electrodes (16) and a series of longitudinal electrodes (18) forming a display matrix (11), and including a control circuit (22) which is fixed to the bottom substrate plate (12) and which includes connection pads (26) connected to the two series of electrodes (16, 18) by conductive paths (41, 42, 44, 46, 48), one part (S.sub.C) of the connection pads (26) being dedicated to addressing the columns (C) of the matrix (11) and another part (S1.sub.L, S2.sub.L) of the connection pads (26) being dedicated to addressing the lines (L) of the matrix (11), characterized in that the control circuit (22) is arranged on a longitudinal end portion (36) of the bottom substrate plate (12), and in that the connection pads (26) addressing the columns (C) are connected to the transverse electrodes (16) and the connection pads (26) addressing the lines (L) are connected to the longitudinal electrodes (18). The invention also proposes a control circuit (22) to be fitted to the display device (10).
