A hypertext display device of the present invention has a user interface for designating an object such as a link text attached contrived for telling an user in HTML data. The recording ink containing at least water, a colorant, a resin fine-particle, a water-soluble organic solvent and a penetrant, in which the penetrant is a diol compound whose carbon number is 7 to 11 and the resin fine-particle is a silicone modified acrylic resin not containing a hydrolyzable silyl group. Each printhead integrated circuit thus formed is configured for backside-connection to the drive circuitry via the through-silicon connectors the contact pads. The projected and recessed part 33 is formed to have different shapes corresponding to the types of the POP panel. The stability controller is programmed to attain a slip rate of about the first and the second wheel at the third wheel, which stabilizes the vehicle in an over-steer condition.
