PURPOSE:To reduce mechanical stress, to eliminate deterioration in quality, and to reduce the cost by allowing a printed wiring board to function as a pattern frame in the electrooptic device consisting of a liquid crystal panel, a polarizing plate, and the pattern frame, and fixing the liquid crystal panel and printed wiring board through the polarizing plate. CONSTITUTION:An opening part for fitting the liquid crystal panel 10 is bored in the printed wiring board 102, the polarizing plate 103 is adhered below it, and then the liquid crystal panel 101 is adhered to the opening part. Then the bonding pad part 105 of the liquid crystal panel 101 and the bonding pad 106 of the printed wiring board 102 are connected and protected with molding resin 108. Then an upper polarizing plate 104 is stuck and then an inter-board connector 109 is soldered to complete a liquid crystal panel module. The polarizing plate 103 absorbs mechanical stress due to the difference in coefficient of heat expansion generated between the liquid crystal panel 101 and printed wiring board 102 and there is no gap between the liquid crystal panel 101 and polarizing plate 103, so a molding agent never flows out and the entry of dust is eliminated. |
