In an image display device in which two light guides are combined, flat plates () of the same material as that of a substrate () of a first light guide () is affixed to the outsides of a first surface () and a second surface () of the substrate (), the first surface () and the second surface () opposing each other. Image light introduced into the substrate () is reflected by an incident-side reflective surface () toward exit-side reflective surface (to), which are half mirrors, and a part of the image light is reflected in stages by the respective exit-side reflective surfaces (and) and the remainder of the image light is transmitted. The image light reflected by the exit-side reflective surfaces (to) is emitted through the second flat plate () and introduced into a second light guide. The part of the image light reflected by the incident-side reflective surface () reaches the interface between the first surface () and the first flat plate (), but enters the flat plate () without being reflected, and hits and is absorbed by a light-absorbing sheet (). This reduces the occurrence of stray light and improves the visibility of a virtual image displayed before user's eyes.

A substrate processing method includes a liquid discharging step of discharging liquid through a nozzle toward a predetermined supply region on the main surface of a substrate held on a substrate holding unit within a chamber, a humidified gas supplying step of supplying humidified gas with a humidity higher than the humidity within the chamber onto the main surface of the substrate to remove electrical charges carried on the substrate, and a spin-drying step of rotating the substrate about a predetermined rotational axis after the liquid discharging step to spin off the liquid component from the main surface of the substrate. The humidified gas supplying step is started before the start of the liquid discharging step and ended at a predetermined termination timing after the start of the liquid discharging step and before the spin-drying step.

Image light that travels between opposed parallel surfaces () of the light guide () while being reflected by the opposed parallel surfaces is partially reflected by the outgoing-side reflection surfaces () of a beam splitter. The image light took out from the light guide () is partially reflected by the two combiners () and advances towards eyes of a user (E). The distance D of the combiners () is set to be equal to or larger than A/(2 cos &#x3b8;&#xb7;tan &#x3b8;) and equal to or smaller than A/(2 cos &#x3b8;&#xb7;tan &#x3b8;), where &#x3b8; is an incident angle &#x3b8; of the image light to the combiner (), Ais a light flux width of the image light reflected by one outgoing-side reflection surface, and Ais a light flux width of the image light emitted from all of the outgoing-side reflection surfaces. This makes it possible to reduce the overlapping of images formed when viewed from the user, avoid the generation of partial image omission, and improve visibility.

Pure water dissolving nitrogen gas and containing microbubbles is supplied to a substrate. Since microbubbles are very minute in size and also have the electrostatic property, they can efficiently adsorb particles on the substrate surface or in the pure water. Further, since pure water dissolving nitrogen gas is unlikely to be charged, the pure water itself never carries new particles from each component of the apparatus. These functions allow efficient particle removal from the substrate surface or the liquid.

Deionized water is supplied into a rinsing bath from its bottom portion and overflows from the upper portion of the rinsing bath to form an upflow of deionized water in the rinsing bath. A substrate is rinsed by being immersed in the upflow of deionized water. After rinsing, the substrate is removed from deionized water, and at this tim the surroundings of the substrate are supplied with vapor of an organic solvent soluble in water which serves to lower surface tension of deionized water to the substrate. Thereafter, the substrate is dried in a sealed chamber that is evacuated and the surroundings of the substrate are reduced in pressure. As a result, during drying the substrate surface after rinsing same with deionized water, it is possible to reduce adhesion of particles to the substrate surface, and to dry the substrate surface rapidly without heating the substrate.
