    • An electro-optical device is capable of high quality images. An electro-optical device (200) includes a first capacitive element (491), a second capacitive element (492), and a third capacitive element (493). The first capacitive element (491) includes a first conductive film (408), a first part of a second conductive film (411), and a first dielectric film (410). The second capacitive element (492) includes a third conductive film (416), a second part of a fourth conductive film (418), and a second dielectric film (417). The third capacitive element (493) includes the third conductive film (416), a third part of the fourth conductive film (418), and the second dielectric film (417). Since a capacitive element that includes a large capacitance value is formed in a narrow region, even if the pixel becomes smaller as the definition is increased, it is possible to realize an excellent electro-optical device in which display defects are suppressed.
    • 电光装置能够获得高质量的图像。 电光装置(200)包括第一电容元件(491),第二电容元件(492)和第三电容元件(493)。 第一电容元件(491)包括第一导电膜(408),第二导电膜(411)的第一部分和第一电介质膜(410)。 第二电容元件(492)包括第三导电膜(416),第四导电膜(418)的第二部分和第二电介质膜(417)。 第三电容元件(493)包括第三导电膜(416),第四导电膜(418)的第三部分和第二电介质膜(417)。 由于在窄区域中形成包含大电容值的电容元件,所以即使像素变得越来越小,也可以实现抑制显示缺陷的优异的电光装置。
