Abstract
A liquid crystal display element comprising drive circuits 56, 57 integrally formed with a drive element 31 on a substrate 32 and two substrates 32, 33 sealed by a sealing agent 67 to include a drive circuit formed portion with a seal area (120), wherein a spacer 66 for determining the gap between the substrates is not contained in a sealing agent but disposed in a display outside area (110). The gap between the electrode substrates is kept constant without damaging the drive circuit and small frame area, so that the liquid crystal device is made compact and lightweight.
