A touch sensor function-equipped display device includes: a first substrate that has a common electrode; a second substrate that is disposed to face the first substrate; a display unit that is disposed between the first substrate and the second substrate; and a touch sensor that detects a touch position on a touch surface disposed on the first substrate side or the second substrate side. The second substrate includes: a plurality of data lines that are aligned in a row direction; a plurality of gate lines that are aligned in a column direction approximately perpendicular to the data lines; a plurality of pixel electrodes that are disposed in each pixel area that is surrounded by a pair of adjacent data lines and a pair of adjacent gate lines; a plurality of capacitance lines that form capacitance with each of the pixel electrodes therebetween; and a plurality of thin film transistors that are disposed for each of the plurality of pixel electrodes and are electrically connected to the pixel electrodes, the data lines, and the gate lines. The touch sensor includes an electric-potential rise rate detecting unit that detects a rise rate of an electric potential of each pixel area at the time of charging by applying a charge signal to the capacitance line and detects a position of the pixel area in which the rise rate of the electric potential detected by the electric-potential rise rate detecting unit is out of a predetermined range as the touch position.

A method for manufacturing a solar cell including a substrate, a first electrode layer, a semiconductor layer, and a second electrode layer, includes forming a first sacrificial layer on a portion of a surface of the substrate; forming the first electrode layer on the substrate and on the first sacrificial layer; and dividing the first electrode layer by removing the first sacrificial layer and a portion of the first electrode layer formed on the first sacrificial layer.

Method for manufacturing solar cell

A liquid crystal device includes a liquid crystal panel, a pair of polarizers and a phase plate. The phase plate is formed by a supply direction of an inorganic material to the substrate surface set such that a ratio of a front phase difference, which is produced when light is incident along a normal direction of the phase plate, and a first phase difference, which is produced when light is incident along a first direction different from the normal direction, falls within a predetermined range.

Liquid crystal device and projector

In a liquid crystal device and a projection display device using the liquid crystal device as a light valve, for the purpose of preventing light incident from opposite the clear viewing direction from affecting the display, in a liquid crystal device ( ), an optical center position ( ) of a microlens ( ) formed on a counter substrate ( ) is offset toward the clear viewing direction as viewed from a center position ( ) of a first opening area ( ) formed for each pixel on the side of an active matrix substrate ( ). For this reason, light incident on the counter substrate ( ) from the direction inclined in the clear viewing direction is emitted from the active matrix substrate ( ); however, light incident from the direction inclined opposite to the clear viewing direction that causes the degradation of contrast is not emitted from the active matrix substrate ( ) and does not affect the display.

The present invention provides a high quality electronic optical device by preventing flaws and dust from adhering on substrates, between which a liquid crystal is inserted, and by suppressing a temperature increase caused by irradiation of light from a light source. The present invention also provides a projection type device using the electronic optical device and a method for producing the electronic optical device. Flaws and dust are never adhered on an outer face of an active matrix substrate because a planar surface of a third substrate is adhered with an adhesive on the outer face of the active matrix substrate in the electronic optical device. Even when flaws and dust are adhered on an outer face of the third substrate, such flaws and dust are not displayed on the projection image. Forming a light-shielding film on the third substrate allows the design margin of a case to be enlarged.

An optical modulation device is presented having a distance Wp from the end of an opposite substrate to the inner peripheral edge of a cover portion in a frame being set to be smaller than the distance W from the end of the opposite substrate to the inner peripheral edge of a first light-shielding portion (Wp<W ). Therefore, there is no fear that incident light from outside of the inner peripheral edge of the cover portion may be blocked by the cover portion, so that incident light may reliably enter the entire image area. This arrangement makes it possible to prevent the peripheral portion of a projection image from becoming dark, and thereby improve the quality of the projection image.
