Abstract

The object of the present invention is to provide a semiconductor display device which has uniform cell thickness and shows a good display characteristic. To achieve the object, in an active matrix type semiconductor display device in which pixel TFTs and driving circuit TFTs are integrally formed on the same substrate, the controlling of cell gaps is performed with gap holding materials arranged between a pixel area and driving circuit areas. As the result, uniform cell thickness is obtained over the whole of the semiconductor display device. Moreover, stress is not generated in the driving circuit TFTs at the time of sticking TFTs substrate together with opposite substrate because conventional grain shaped spacers are not used in this device. Thus, damage is prevented from being provided on the driving circuit TFTs.
