A liquid crystal display comprises a first substrate on which are provided a matrix (12) of pixels (11) and drive systems (13, 14) for driving the matrix of pixels with pixel signals, a second substrate opposed to the first substrate, and a liquid crystal layer held between the substrates. The drive systems (13, 14) are controlled by control systems (23, 24, 25), which are implemented in a semiconductor chip on the first substrate by a COG method to make the whole device compact. L'invention concerne un écran à cristaux liquides comprenant un premier substrat sur lequel sont disposés une matrice (12) de pixels (11) et des systèmes d'entraînement (13, 14) pour entraîner la matrice avec des signaux pixels, un deuxième substrat faisant face au premier et une couche de cristaux liquides entre les deux substrats. Les systèmes d'entraînement (13, 14) sont pilotés par des systèmes de commande (23, 24, 25) implantés dans une puce à semiconducteur sur le premier substrat selon le procédé de puce sur support en verre pour obtenir un dispositif compact.
