<p>PURPOSE: To improve the black mask structure of a driving circuit-incorporating type display device, to moderate alignment accuracy and to secure the reliability of a driving circuit. CONSTITUTION: This display device has panel structure where a driving substrate 1 and a counter substrate 2 are bonded to each other, and electrooptical substance is held between both substrates. The driving substrate 1 is divided into a screen part 3 and a peripheral part 4. A pixel electrode and a switching element are integrated and formed on the screen part 3. Driving circuits 5, 6 and 7 driving the switching element are integrated and formed in the peripheral part 4. A light shielding film is formed by patterning corresponding to the switching element on the screen part 3 on the inner surface side of the driving substrate 1 so as to constitute a black mask. A light shielding plate 8 is attached to surround the screen part 3 along the peripheral part 4 on the outer surface side of the driving substrate 1 or the counter substrate 2, thereby, the driving circuits 5, 6 and 7 are shielded from the light.</p> |
