The present invention provides a diagnostic method for stroke/asymptomatic cerebral infarction and a screening method for patients with stroke/asymptomatic cerebral infarction, which comprise measuring acrolein content or polyamine content; or polyamine oxidase activity or protein content of polyamine oxidase in plasma. The knowledge of the present invention indicates the possibility of preventing, inhibiting the progression of stroke/asymptomatic cerebral infarction by inhibiting polyamine oxidase, and the possibility of obtaining a therapeutic agent for stroke/asymptomatic cerebral infarction by searching for compounds that inhibit polyamine oxidase.

Method of diagnosing apoplectic stroke/asymptomatic brain infarction using acrolein content

A liquid crystal display includes pixels each having an switching element, drain drivers and gate drivers for operating the switching elements and the pixels, and drain lines and gate lines supplying signals from the drain drivers and the gate drivers to the switching elements being formed on one of a pair of substrates sandwiching a liquid crystal layer. Wiring lines are formed on the one of a pair of substrates for transferring display data signals and a clock signal to the gate drivers.

Driving method for display device

An object of the present invention is to provide a liquid crystal display device including a back light in which an electrode support member can be reliably arranged on the base side without concern for thermal expansion. There is provided a liquid crystal display device comprising: a liquid crystal display panel; and a back light arranged on the back surface of the present liquid crystal display panel; wherein the back light is composed of a plurality of bar light sources arranged in parallel in a plane opposing the liquid crystal display panel and a base that supports each of the bar light sources through electrode fittings at electrode sections; wherein the electrode fittings are provided on electrode support members extending in a direction in which the bar light sources are arranged in parallel, in units of the electrode fittings that support a mating electrode section of each bar light source; and wherein the electrode support member includes a portion fixed to the base side at least one point and a portion covered by a projecting portion fixed to the base side at another point, along the extending direction of the electrode support member.

Liquid crystal display device

There is disclosed a display device having a display panel which is prevented from being scratched if an optical member such as a diffusive plate located behind the display panel swings. The display device has the display panel, an array of light sources disposed behind the display panel, and the optical member disposed between the display panel and the array of light sources. The distance between a first end of the optical member and the display panel is set greater than the distance between a second end of the optical member and the display panel, the second end being opposite to the first end.

Display device

A subject of the present invention is to provide a liquid crystal display device in which the reliability of electrical connection between electrodes and electrode fittings can be improved even if there are variations in diameter of the bar light sources arranged in the back light. There is provided a liquid crystal display device comprising: a liquid crystal display panel; and a back light arranged on the back surface of the present liquid crystal display panel; wherein the back light is composed of a plurality of bar light sources arranged in parallel in a plane opposing the liquid crystal display panel and a base that supports each of the bar light sources through electrode fittings at electrode sections; wherein the electrode fittings are each provided with a pair of pressing portions which press the circumferential surface of the electrode of the bar light source from opposing sides of the circumferential surface; and wherein each of the pressing portions is arc-shaped such that the pressing portion surface facing the circumferential surface of the electrode of the bar light source has a concave; and is formed such that the pressing portion presses the electrode of the bar light source through projections formed on the concave.

A liquid-crystal display device includes a liquid-crystal display panel having a liquid-crystal layer sandwiched between a pair of substrates, and a backlight unit provided on a surface opposite to a display surface of the liquid-crystal display panel. The backlight unit has an accommodator capable of having at least one optical sheet arranged therein and having a sidewall having a projection at a periphery thereof. The optical sheet has a hole into which the projection is inserted, the hole formed in the optical sheet having a form that is the same as the top plan form of the tip of the projection, the hole being formed in the optical sheet so that a certain rotation angle is established between the form of the hole and a top plan form of the tip of the projection in a state in which the optical sheet is accommodated in the accommodator.

Liquid-crystal display device

A display device includes: a reflection plate; plural light sources disposed above the reflection plate; an optical member disposed above the plural light sources; a support member disposed standing on a bottom surface of the reflection plate; a frame member that houses the reflection plate and the light sources; and a display panel disposed above the optical member. The support member includes: a standing support portion that is disposed standing on and supports the reflection plate; an optical member support portion that supports the optical member; and a leg portion that protrudes downward of the reflection plate and the frame member and is bent in a direction along the standing support member.

Display device and method of assembling the display device

Optical sheets can be fixed easily and positively in a liquid-crystal display device having a liquid-crystal display panel in which a liquid-crystal layer sandwiched between a pair of substrates and a lighting unit provided on a surface opposite to a display surface of the liquid-crystal display panel. For this purpose, a projection is provided on a sidewall of an accommodator, and the projection is inserted into a hole provided in optical sheets arranged within the accommodator, thereby fixing the optical sheets in the accommodator. The length along a certain straight line of a top plan form of a tip of the projection is longer than the length along the certain straight line of the hole formed in the optical sheets, thus preventing the optical sheets from falling out of the accommodator.

A liquid crystal display device includes a driver circuit for outputting a charging voltage at a beginning of a horizontal scanning period and then a gray scale voltage corresponding to a display data to a video signal line. The liquid crystal display device is driven by inverting a polarity of the gray scale voltage on a pixel electrode with respect to a common voltage on a common electrode every N lines of scanning lines, where N&#x2267;2 and by making a first charging time of the charging voltage corresponding to a first line of N lines of the scanning lines scanned immediately after inversion of the polarity of the gray scale voltage different from a second charging time of the charging voltage corresponding to a second line of the N lines scanned immediately succeeding the first line.
