Abstract
An electro-optical device includes a display electrode disposed in an image display region of a TFT array substrate, a pattern portion including at least one of wiring and a circuit element connected to the display electrode directly or through a pixel switching element and provided in a frame region, which defines the periphery of the image display region, and a lower shielding film for covering the TFT array substrate side of at least a portion of the pattern portion. Therefore, in the electro-optical device such as a liquid crystal device, a light-dark pattern due to the wiring and the circuit element provided in the frame region can be prevented from being projected near the edge of a display image.
Claims29
An electro-optical device comprising:
- a display electrode disposed in an image display region of a substrate;
- a pattern portion comprising at least one of wiring and a circuit element connected to the display electrode directly or through a pixel switching element and provided in a frame region, which defines the periphery of the image display region;
- and
- a lower shielding film for covering the substrate side of at least a portion of the pattern portion.
An electro-optical device comprising:
- a display electrode disposed in an image display region of a substrate;
- a pattern portion comprising at least one of wiring and a circuit element connected to the display electrode directly of through a pixel switching element and provided in a frame region, which defines the periphery of the image display region;
- a first lower shielding film for covering the substrate side of at least a part of the pattern portion;
- and
- a second lower shielding film comprising the same film as the first lower shielding film and formed in the frame region except in the region where the pattern portion is formed.
An electro-optical device comprising:
- a display electrode disposed in an image display region of a substrate;
- a pattern portion comprising at least one of wiring and a circuit element connected to the display electrode directly or through a pixel switching element and provided in a frame region, which defines the periphery of the image display region;
- a lower shielding film for covering the substrate side of at least a portion of the pattern portion;
- an in-region shielding film comprising the same film as the lower shielding film and formed to cover the substrate side of the channel region of a second transistor serving as the pixel switching element;
- and
- an out-of-region shielding film comprising the same film as the lower shielding film and the in-region shielding film, and formed in at least a portion of a peripheral region around the image display region, the peripheral region including the frame region.
